چکیده انگلیسی
Chitosan microsphere (CS) was prepared by phase-inversion method as the support matrices. Cibacron Blue F3GA (CB) was covalently attached to the chitosan microspheres, and thus the novel dye-affinity adsorbent was obtained. These Cibacron Blue F3GA-attached chitosan microspheres (CB-CS) were used in the catalase (CAT) adsorption studies. The maximum CAT adsorption capacity of Cibacron Blue F3GA-attached chitosan microspheres was 28.4Â mg/g at pH 7.0. Langmuir adsorption model was found to be applicable in interpreting CAT adsorption. Significant amount of the adsorbed CAT (up to 90.6%) was eluted in the elution medium containing 0.5Â M NaSCN at pH 8.0. It appears that CB-CS can be applied for adsorption of CAT without causing any denaturation.
