Özet

In this study, graphene oxide (GO) filled sodium alginate membranes were synthesized and used for pervaporative desalination studies. The morphological, structural, thermal, and mechanical properties of membranes were determined. In the desalination studies, the effect of temperature and GO content on the separation performance was investigated. The addition of GO improved both the mechanical and thermal properties of the membrane as well as the separation performance. Higher than 99.4% of total rejection values were achieved by all the membranes at all studied temperatures. The flux value gradually increased from 1.63 kg/m(2).h to 4.89 kg/m(2).h when the GO concentration in the matrix increased from 0 wt% to 2 wt%. The highest flux of 8.11 kg/m(2).h with a rejection of 99.41% was obtained at 60 degrees C by using 2 wt% of GO loaded alginate membrane. The highest rejection of 99.95% with a flux of 3.46 kg/m(2).h was achieved at 40 degrees C by using 1 wt% of GO filled alginate membrane.
