摘　　要：比较酸－酸－碱－碱和酸－碱－酸－碱法制备甲壳质方法的异同；得到脱乙酰度为８６％的壳聚糖，用原子吸收法测定锌、铅、铜、镉四种重金属的含量，用其处理渔业废水，ＣＯＤ去除率达７４％．Stated and compared the difference in two methods of producing chitin Acid Acid Base BaseandAcid Base Acid Base.Obtaining chitosan with deacety lation degree by 86%.The contents of four heavy metals Zn 2+ 、Cu 2+ 、Pb 2+ 、Cd 2+ were determined by Abs.Fishing waste water was treated by this method,the COD rate reaches 74%.
