Separation of copper ions from iron ions using PVA-g-(acrylic acid/N-vinyl imidazole) membranes prepared by radiation-induced grafting.

摘要: Acrylic acid (AAc), N-vinyl imidazole (Azol) and their binary mixtures were graft copolymerized onto poly(vinyl alcohol) membranes using gamma irradiation. The ability of the grafted to separate Cu ions from Fe was investigated with respect grafting yield pH feed solution. data showed that diffusion copper compartment receiver depends on To contrary, iron did not diffuse through all yields. However, a limited amount diffused in strong acidic medium. This study shows prepared could be considered for separation ions. temperature thermal decomposition pure PVA-g-AAc/Azol membrane, membrane containing ions, determined TGA analyzer. It shown presence increases temperature, bonded are more stable than those
