Cerium dioxide nanoparticles decorated on CuFe2O4 nanofibers as an effective adsorbent for removal of estrogenic contaminants (bisphenol A and 17-alpha ethinylestradiol) from water
CeO2/CuFe2O4 nanofibers with high adsorption selectivity for bisphenol A (BPA) and 17-alpha ethinylestradiol (EE2) were synthesized by support of CeO2 on the CuFe2O4 nanofibers. The characteristics of nanocomposite were investigated via using XRD analysis, FT-IR, SEM, pH(pzc), and Brunauer, Emmett, and Teller methods. The results showed that the maximum adsorption capacities of adsorbent for BPA and EE2 were 226.9 and 179 mg g(-1), respectively. Moreover, the regeneration experiments illustrated that synthesized adsorbent could be recovered, and it showed good recycling ability after being used for six cycles. The isotherm analysis indicated that the equilibrium data could be represented by the Langmuir-Freundlich model. The thermodynamic study showed that the adsorption processes were spontaneous and endothermic under studied conditions.
