摘要
应用羧甲基壳聚糖对水中Cd2+离子进行絮凝处理，研究了溶液的酸度、温度、絮凝时间以及电解质的相对量等因素对除镉率的影响。研究表明，在最佳条件下，用此法处理含镉浓度在30～50ms／L的水样，除镉率可达99．9％以上。本文还对羧甲基壳聚糖除镉机理进行了初步探讨。
A flocculation method for removing cadmium in water by use of carboxy-methyl chitosan,in presence of an electrolyte Na2SO4 is described. The experiment indicated that the rate of removing Cd2+ by this method of water treatment could reach over 99. 9 %,under the best condition. The mechanism of removing cadmium was also concerned.
