摘要:
用虾皮作为原料制取甲壳素，然后用氢氧化钠溶液对甲壳素进行浸泡，用微波脱去其乙酰基和蛋白质，制得壳聚糖.制备条件为：氢氧化钠溶液质量浓度 40％，微波功率 400 W，微波反应时间 10 min.所得产物用红外光谱进行表征.以制备的壳聚糖配成0.2%的溶液作为絮凝剂，通过单因素实验和正交实验，研究其对水源水浊度的处理效果和最佳工艺条件.结果表明壳聚糖絮凝剂去除水源水浊度的最佳单因素实验条件为：絮凝剂投加量为3 mL/L，水源水pH值调到8，混合阶段转速设定为130 r/min，混合时间设定为30 s，反应阶段转速设定为30 r/min，反应时间设定为15 min，沉淀时间设定为15 min.正交实验的最佳组合水平为：投加量为3 mL/L，pH值为10，沉淀时间为25 min，混合转速为130 r/min.
Abstract:
Chitin was prepared from shell of shrimp，then it was soaked in the solution of NaOH，and it was deacetylated and deproteinized under microwave irradiation. The optimal concentration of NaOH was about 40%, the optimal power of microwave was 400 W, and the reacttime of microwave was 10 min. Under these conditions, the chitosan could produced at a time. The product was characterized by infrared spectrometer. The experiment from onefactor analysis of variance researches on treatment effect and best process conditions of 0.2% chitosan solution as a flocculant to treat drinking water source were studied. The results show that the best onefactor experimental conditions are chitosan of 3 mL/L, pH of 8, mixspeed of 130 r/min, mixtime of 30 s, reactspeed of 20 r/min, reacttime of 15 min, sedimentationtime of 15 min. And the best assemble level of orthogonal experiment is chitosan of 3 mL/L, pH of 10, sedimentationtime of 25 min, mixspeed of 130 r/min.
