摘要
Abstract
In this study,the hot water extraction method was utilized to extract polysaccharides from persimmon peel,and the persimmon peel polysaccharides were combined with trivalent chromium ions to prepare persimmon peel polysaccharide chromium.Considering the adsorption rate of chromium as the index,the adsorption process of persimmon peel polysaccharide chromium was optimized using single factor and response surface methodology.The results showed that the optimal preparation process of persimmon peel polysaccharide chromium consisted of the following steps,such as the mass ratio of persimmon peel polysaccharides to chromium chloride was set at 6.7:1;the reaction time was 150 min;the temperature was set at 82 ℃;and the pH of the adsorption liquid was fixed at 5.Under these conditions,the maximum adsorption rate reached 92.81％.Therefore,this study has shown that persimmon peel polysaccharides can efficiently bind trivalent chromium ions,which can further provide technical support for the development of green pollution-free heavy-adsorption chromium adsorbents or animal nutritional supplements.关键词
