Abstract:
Attapulgite-chitosan complex was prepared for use in removing cadmium from glycosaminoglycan-rich enzymatic hydrolysates of the entire viscera of Ostrea rivularis Gould. The influence of hydrolysate pH, shaking speed and time, and complex-to-hydrolysate ratio on cadmium removal rates and glycosaminoglycan recovery was explored. By using response surface methodology, the optimized experimental conditions were obtained as hydrolysate pH 7.2, addition of the complex in a proportion of 6.4 mg/mL, and shaking at a speed of 170 r/min for 30 min. The removal rate of cadmium under these conditions was 73.7%, and the recovery of glycosaminoglycan was 44.1%. This study indicates that attapulgite-chitosan complex can effectively remove cadmium from glycosaminoglycan from Crassostrea rivularis, with no significant impact on the recovery of glycosaminoglycan.
