Adsorption of vitamin B12 in aqueous solutions by poly(N-isopropylacrylamide/ itaconic acid) copolymeric hydrogels

Poli(N-izopropilakrilamid/itakonik asit) kopolimerik hidrojelleri tarafından sulu çözeltilerde vitamin B12 adsorpsiyonu


N-isopropylacrylamide/itaconic acid copolymeric hydrogels (NIPAAm/IA) containing different quantities of itaconic acid have been irradiated with g radiation. The hydrogels were used in an experiment concerning the uptake and release behavior of Vitamin B12. In the experiment of the adsorption of Vitamin B12, type S ad- sorption isotherm was found. The effect of comonomer concentration and irradiation dose on the uptake and release behavior of the hydrogels was studied.
