Öğe Adsorption and removal of Cu (II) ions from aqueous solution using pretreated fish bones(Elsevier Science Bv, 2010) Kizilkaya, Bayram; Tekinay, A. Adem; Dilgin, YusufPretreated fish bones obtained from engraulis European anchovy (Engraulis encrasicolus), European anchovy (Sardine pilchardus), bogue (Boops boops), bluefish (Pomatomus saltatrix) and gilthead seabream (Sparus aurata) were used as natural, cost-effective, waste sorbents for the adsorption and removal of copper from aqueous systems. The removal efficiency of the adsorbent was investigated as a function of pH, contact time, initial metal concentration, temperature, cleaning process, fish species and adsorbent dose. The maximum adsorption capacity was 150.7 mg/g at optimum conditions. The kinetic results of adsorption obeyed a pseudo-second-order model. Copper adsorption fitted the Langmuir isotherm. Delta H-0 value was 12.9 kJ/mol indicating that the adsorption mechanism was endothermic. The activation energy, E-a, was determined as 52.9 kJ/mol. Weber-Morris and Urano-Tachikawa diffusion models were also applied to experimental equilibrium data. The fish bones were effectively used as a sorbent for the removal of Cu ions from aqueous solution. (C) 2010 Elsevier B.V.

Adsorption procedure was used for the preparation of the modified electrodes. It was observed that PGE/QH(2) showed a significant electrocatalytic activity toward sulfide oxidation. Cyclic voltammetric studies show that the peak potential of sulfide shifts from +450 mV at bare PGE to +280 mV at PGE/QH(2). The electrocatalytic currents obtained from amperometric measurements at +300 mV vs. Ag/AgCl/KClsat and at pH 8.0 BR buffer solution containing 0.1 M NH4Cl were linearly related to the concentration of sulfide. The calibration graph consisted of two linear segments of 1-20 mu M and 20-800 mu M with a detection limit of 0.3 mu M (based on 3s(b)). The proposed method was successfully applied to the determination of sulfide in waste waters and was compared with the spectrophotometric method. (C) 2012 Elsevier B.V.

After ZnS-CdS film was electrochemically deposited onto PGE surface, GOD was immobilized on the surface of ZnS-CdS/PGE through crosslinking with chitosan (CT). A pair of well-defined reversible redox peak of GOD was observed at GOD/CT/ZnS-CdS/PGE based on enzyme electrode by direct electron transfer between the protein and electrode. Further, obtained GOD/CT/ZnS-CdS/PGE offers a disposable, low cost, selective and sensitive electrochemical biosensing of glucose in FIA system based on the decrease of the electrocatalytic response of the reduced form of GOD to dissolved oxygen. Under optimum conditions (flow rate, 1.3 mL min(-1); transmission tubing length, 10 cm; injection volume, 100 mu L; and constant applied potential, -500 mV vs. Ag/AgCl), the proposed method displayed a linear response to glucose in the range of 0.01-1.0 mM with detection limit of 3.0 mu M. The results obtained from this study would provide the basis for further development of the biosensing using PGE based FIA systems. (C) 2015 Elsevier B.V.

There, however, are limited studies that look at the impacts of water stress at different vegetative periods. For this reason, in this study, different levels of water treatment (0%, 30%, 70%) were applied to red cabbage at two stages of development (early and late vegetative) in a two-year field study. The effect of water stress on the major antioxidant compounds, as well as on yield and some morphological parameters were investigated. According to the findings, the least yield loss (22%) occurred in the early vegetative period of the second-year trial where 70% irrigation water was applied, while the highest yield loss (56%) was obtained during the early vegetative period of the first-year trial where no irrigation was applied. Biochemical analyses revealed that the highest accumulation of flavonoids, 0.83 mg g(-1), and anthocyanins, 1.51 mg g(-1), occurred in the early vegetative period with the trial that received no irrigation treatment. The phenolic compound content was determined as 1.62 mg g(-1), and the antioxidant capacity was found to be 1.93 mg g(-1) during the late vegetative period in the trials without irrigation treatment. These findings suggest that in regions with limited water resources, water conservation can be practiced during different vegetative periods in order to get higher biochemical benefits with a lower yield loss when cultivating red cabbage.Öğe Comparative Study and Removal of Co and Ni (II) Ions from Aqueous Solutions Using Fish Bones(Amer Scientific Publishers, 2011) Kizilkaya, Bayram; Tekinay, A. AdemIn the present study, removal of cobalt and nickel (II) ions from aqueous solutions was studied by using pretreated fish bones. The effect of pH, contact time, temperature and metal concentration on the removal capacities of the adsorbent was investigated. The maximum removal capacities for Co and Ni (II) were found to be 83.70 and 58.82 mg/g at optimum conditions (p < 0.05), respectively. The experiments showed that when pH increased, an increase in the removal capacity of the pretreated fish bones was observed. The kinetic results of removal obeyed a pseudo second-order model. Freundlich and Langmuir isotherm models were applied and it can be suggested that the experimental data for the adsorption of Co and Ni (II) on the bone sorbents fit the Langmuir isotherm model. The values of R-L for Co and Ni (II) were found to be 0.50 and 0.25, respectively. The thermodynamic parameters related to the adsorption process such as E-a, Delta G(0), Delta H-0 and Delta S-0 were calculated. Delta H-0 values (positive) of cobalt and nickel showed that the adsorption mechanism was endothermic. Weber-Morris and Urano-Tachikawa diffusion models were also applied to the experimental equilibrium data. Based on the results, it can be concluded that fish bones can be used as adsorbent to remove Co and Ni (II) from aqueous solutions with simple processing.Öğe Comparative Study of Biosorption of Heavy Metals Using Living Green Algae Scenedesmus quadricauda and Neochloris pseudoalveolaris: Equilibrium and Kinetics(Taylor & Francis Inc, 2012) Kizilkaya, Bayram; Turker, Gulen; Akgul, Riza; Dogan, FatihThe biosorption of several heavy metals such as cobalt(II), chromium(III), lead(II), cadmium(II), nickel(II), and manganese(II) from aqueous systems on living microalgae cultures, Scenedesmus quadricauda and Neochloris pseudoalveolaris were studied under laboratories conditions. The kinetic and statistical parameters were calculated by using the data obtained from batch cultivation and well fitted a pseudo-first-order rate equation. The initial metal concentrations in solution were about 5-40 mg . L-1. According to the pseudo-second-order model, the biosorption capacities of Scenedesmus quadricauda for Co(II), Cr(III), Pb(II), Cd(II), Ni(II), and Mn(II) ions were found in the ranges of 2.14-52.48, 1.98-81.98, 8.05-4.26, 7.81-24.96, 2.17-55.71, and 3.54-75.20 mg g(-1), respectively. Kinetic studies revealed that the metal uptake capacity of each living green algae was rather fast. It was also observed that the biosorption kinetic rate decreased with increasing concentration for both microalgae. The application of diffusion-controlled models to the experimental results indicated that the contribution of intraparticle diffusion to the overall sorption kinetics was not very important. Results showed that Co(II), Cr(III), Pb(II), Cd(II), Ni(II), and Mn(II) ions could effectively be absorbed by using living microalga cultures from aqueous solutions.Öğe Crude Protein Values and Amino Acid Profiles of Some Red Algae Collected from Canakkale(Natl Inst Science Communication-Niscair, 2015) Akgul, Riza; Kizilkaya, Bayram; Akgul, Fusun; Ormanci, Hasan BasriPresent study consists the total protein values and amino acids components of the some red algae, collected from coastal zones of the Dardanelles and inland water. Crude proteins of samples Were determined by the Kjeldahl method and were calculated using a nitrogen conversion factor of 6.25. Levels of amino acids were measured in algae samples using gas chromatography. Total protein contents were 36.72% in Batrachospermum gelatinosum (Linnaeus) De Candolle, 32.3% in Ceramium rubrum var. barbatum G. Feldmann-Mazoyer, 27.84% in Lemanea fluviatilis (Linnaeus) C. Agardh and 19.5% in Phyllophora crispa (Hudson) P.S. Dixon. In all, thirty two amino acids were identified and estimated. Analysis revealed the presence of eight free essential, nine free non essential and fifteen other amino acids. Aspartic acid was the major constituent in all the samples. Kinds and percentage of amino acids vary according to algae.Öğe Determination of Organic Acid Composition and Free Radical Scavenging Capacity of Kefir(Asian Journal Of Chemistry, 2014) Turker, Gulen; Kizilkaya, Bayram; Arifoglu, NazanThe organic acid composition as well as the free radical scavenging capacity of kefir produced from different kinds of milk was investigated. The organic acid composition of the samples was determined by high performance liquid chromatography (HPLC), while free radical scavenging capacity was evaluated spectrophotometrically. Oxalic acid, acetic acid, citric acid and succinic acids were found to be significantly higher in kefir produced from cow milk (p < 0.05), while malic acid and lactic acid were significantly higher in kefir produced from goat milk (p < 0.05). The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity of kefir produced from goat milk was significantly higher than that of kefir made from cow milk (p < 0.05). There was a high correlation between the malic acid and lactic acid formation and the free radical scavenging activity of the samples, implying that the formation of these organic acids during kefir production positively enhances the free radical scavenging capacity of the fermented milk products.Öğe Determination of some nutritional compositions of roe samples of the edible sea urchin Paracentrotus Lividus (Lamarck, 1816) in the Dardanelles (Marmara Sea)(Natl Inst Science Communication-Niscair, 2015) Kizilkaya, Bayram; Ozalp, H. Baris; Turker, Gulen; Alparslan, Mustafa; Tekinay, A. AdemIn this study, the nutritional composition of gonad samples of Paracentrotus lividus collected from three different stations in the Sea of Marmara (Dardanelles) and the Northern Aegean Sea, Bozcaada Island during the summer season of 2012 was investigated. As a purpose of the research, the effect of total carotenoids and free radical-scavenging activity assay of three different extracts (methanol, acetone and chloroform extracts) have been determined. Total carotenoids were found to range between 131 and 179 mu g/g of sea urchin. The current study shows that the highest inhibition was found as 99.1 (%) in methanolic extract sampled from Tuzburnu (the first station). Macro (Ca, Na, K and Mg) and micro (Cu, Fe, Mn and Zn) mineral composition of urchins was specified by ICP-OES. Results show that sea urchin was found to be rich in total carotenoids, antioxidant capacity, macro and micro minerals.Öğe Determination of total Carotene and Chlorophyll contents of tellina (Donax trunculus Linnaeus, 1758) using UV spectrophotometer in Black Sea(Arman Darya Inc, 2020) Tan, Evren; Kizilkaya, BayramPresent study investigates monthly changes of the total carotene and chlorophyll a content of tellina (Donax trunculus Linnaeus, 1758) from Kefken territory on the Black Sea coast between 2013 and 2014. The total carotene and chlorophyll analysis was determined by UV spectrophotometer. Three different calculation methods were used for total carotenoid calculation. The methods that have been chosen are comparable with the available methods in the literature. The highest carotene amount was determined in March about 78.91 mu g/g as Car 2 (secondary carotene calculation method). Furthermore, the lowest carotene amount was determined in November. The highest and the lowest amount of chlorophyll-a was detected in July about 84.90 +/- 2.60 mu g/g and June about 8.11 +/- 0.39 mu g/g, respectively. It is possible to say that tellina can be consumed as food. In respect of the detections in this study, it can be said that tellina can be conveniently consumed between February and July depending on the territory.
