摘　　要：将羧甲基淀粉(CMS)作为重金属捕集剂,研究pH值、投药量、反应时间、CMS取代度等条件对主要重金属污染物Pb的去除规律;并初步探讨了去除机理,获得去除Pb的最佳条件。从CMS本身的结构特点以及对水中铅较好的去除效果来看,认为CMS在处理重金属污水方面具有广阔前景。By using Sodium Carboxymethyl Starch (CMS) as capturing agent for heavy met al, the optimum condition for the removal of Pb was studied, including pH value, the dosage of CMS, reaction time and the degree of substitution, and the remova l regularity was approached from which the best removal condition for Pb was obt ained. It was suggested that there would be a prosperous future in the disposal of wastewater with heavy metal considering from the CMS’s structure and the per formance.
