摘要
考察了盐酸浓度、处理时间对海泡石的脱镁率及比表面和孔径分布等的影响． 结果表明，当脱镁率为３６ ％ 时，海泡石的比表面有最大值，达５５４－４ ｍ２／ｇ，对Ｐｂ２ ＋ ，Ｃｄ２ ＋ 的吸附性能也最好．吸附行为可用Ｌａｎｇｍｕｉｒ 吸附等温方程来关联．
The effects of HCl acid concentration and treatment time on the removed magnesium ratio, surface and pore structures of sepiolite have been investigated. The results show that with removed magnesium ratio of 36%, the treated sepiolite has a maximum surface area of 554 4 m 2/g , therfore a better adsorability towards Pb 2+ and Cd 2+ . The adsorptive behavior can be related to the Langmuir isothermal adsorption equation.
