Bamboo charcoal modified by polyaspartic acid (PAsp) was used for the removal of cadmium from shellfish enzymatic hydrolysates. The effects of pH, adsorption time, bamboo charcoal dosage and temperature on the cadmium removal rate were investigated, and the conditions of cadmium removal were optimized by response surface method. The cadmium removal rate was up to 96.59% when pH is 5.0, adsorption time is 25 min, and the bamboo charcoal dosage is 0.26g in 10mL enzymatic hydrolysate. Therefore, PAsp modified bamboo charcoal can significantly improve the efficiency and ability of adsorbing cadmium, and can be used for the removal of cadmium from shellfish enzymatic hydrolysates.
