The chitosan microspheres were prepared by inverse phase suspension method.The chitosan was cross-linked with epoxychoropropane.And the structure of microspheres was characterized by FTIR and SEM.The effects of the adsorption time,pH,temperature,concentrations of albumin bovine and sodium chlorind on the adsorption efficiency of albumin bovine were studied.The experimental results indicated that microspheres were insoluble in acidic and basic solutions.The microspheres adsorbed albumin bovine very well and ...
