dc.description.abstractPolyphosphazenes have an important place in material science because they allow functional diversity to be realized easily. In this study, for the first time, synthesis of cyclomatrix-type poly-(cyclotriphosphazene-co-4-(aminomethyl)-1,8-octanediamine) (Phz-AO) particles including different surface features and dimensions have been reported using different stoichiometric ratios of hexachlorocyclotriphosphazene and 4-(aminomethyl)-1,8-octanediamine. The use of Phz-AO (1:2) submicroparticles with spherical form and average dimension of 647.82 ± 22.23 nm as an adsorbent was researched for methyl orange (MO) anionic azo dye. Submicrospheres had significant potential for adsorption of negative charged MO and maximum adsorption capacity of 1244.7 mg.g − 1. The submicrospheres displayed high adsorption potential at pH ≤6 conditions thanks to their surface amine groups. The maximum adsorption capacity in synthetic textile wastewater was 912.75 mg.g−1 as experimental. While the adsorption kinetics had the pseudo second order model, the most suitable model for adsorption was the Langmuir isotherm. The thermodynamic parameters for MO adsorption with submicrospheres were 10.02 ± 1.81 kj.mol−1 for ΔH°, 61.08 ± 5.74 j.mol−1.K−1 for ΔS° and ΔG° (kj.mol−1)<0. In light of all data obtained, the Phz-AO (1:2) submicrospheres which can be easily prepared with a single-step reaction are expected to be a remarkable member of the super adsorbent material family.en_US
