Study on preparation and properties of tannins immobilized chitosan-Ce4+ resins

The tannins immobilized chitosan-Ce4+ resins (TCCR) were prepared. The optimum conditions on activating and coupling of chitosan resins were obtained by means of orthogonal design experiments. TCCR were characterized by DSC and FT-IR. The adsorption capacity for bovine serum albumin (BSA) of TCCR was investigated. The results show that TCCR have an excellent adsorption capacity for BSA in water, comparing with chitosan-Ce4+ resins (CCR). The TCCR can be a novel functional material for removal protein in some beverages.
