摘　　要：以高岭土为基本原材料制备壳聚糖插层高岭土复合吸附材料,并采用红外光谱(FTIR)、X-射线衍射(XRD)、电镜扫描(SEM)对其结构和形貌进行了表征。研究了复合吸附剂对实际铅酸蓄电池厂含铅废水进行了处理。结果表明:壳聚糖/高岭土复合吸附剂对Pb2+的去除率为99.1%,处理后的水达到了国家一级排放标准。The study is made on the disposal of the lead-containing waste water in the lead-acid battery plant with the compound adsorbent of kaolinate/chitosan with kaolinate as its basic raw materials with whose structure and appearance were characterized by FTIR,XRD,SEM. Results showed that the adsorption rate of compound adsorbent towards Pb^2＋ was over 99.1% and the treated effluent met Grade I of national wastewater discharge standard.
