【摘要】 本文报道了用海虾壳为原料制取中粘度、脱乙酰基66.17％的壳多糖,在电解质存在下絮凝除镉的方法。用此法处理含镉浓度在20—40mg/l的水样,除镉率可达99.9％以上,脱乙酰壳多糖与电解质混用的摩尔比为1.14∶1。本文还探讨了电解质的作用机理。更多还原

【Abstract】 A flocculation method for removing cadmium in water by use of chitosan shell with a middle viscosity and 66% deacylation, in presence of an electrolyte is described. By this method of water treatment, when cadmium ion concentrations of 20-40mg/l and a molar ratio of chitosan & electrolyte of 1,14:1 were used, the removal could reach more that 99.9%. The mechanism of the action of the electrolyte is discussed.更多还原
