Özet
In this study, $Fe^{3+}$ adsorption was carried by using supermacroporous poly(2-hydroxyethyl methacrylate-Nmethacryloyl-(L)-histidine methyl ester) [poly(HEMA-MAH)] cryogel. Poly(HEMA-MAH) cryogel was characterized by swelling tests and scanning electron microscopy. The influence of flow rate, pH, initial $Fe^{3+}$ concentration, and $Fe^{3+}$ adsorption from human plasma effected with beta thalassemia on the adsorption efficiency of the cryogel was investigated. The equilibrium swelling degree of poly(HEMA-MAH) cryogel was found to be 7.54 g $H_2$O/g cryogel.$Fe^{3+}$ adsorption capacity of poly(HEMA-MAH) cryogel from aqueous solution was estimated as 1.79 mg/g cryogel, while lower adsorption capacity was observed in human plasma (1.71 mg/g). It was also observed that $Fe^{3+}$ could be repeatedly adsorbed and desorbed using poly(HEMA-MAH) cryogel without significant loss in its adsorption capacity.
