摘　　要：采用稀HCl浸取,ICP-AES测定硅藻土助滤剂表面吸附铅的含量,并研究了浸取时间、温度、浸取剂浓度及助滤剂/浸取剂固液比对浸出铅含量的影响。方法简便、快捷,方法精密度为2.78%—6.29%,回收率在96.0%—103.3%之间,检出限为0.026μg/mL。The absorbed Pb in diatomite filter aids was extracted by diluted HC1, and determinated by inductively coupled plasma atomatic emission spectrometry（ICP-AES）. The influence of extraction time, extraction temperature, extracting agent concentration and ratio of diatomite （g）/extracting agent（mL） was studied. The RSD is 2. 78%--6.29%,the recovery is from 96.0% to 103.3%, and detection limit is 0. 026μg/mL. The method is accurate, simple, rapid for the determination of adsorbed Pb in diatomite filter aids.
