摘　　要：采用离子交换法以盐酸作为质子供体对海泡石进行酸化处理,用CTMAB对其进行改性。探讨了改性海泡石用量、时间、pH、温度、初始浓度等对Pb^(2+)吸附性能的影响。实验结果表明:经过酸处理和CTMAB改性海泡石对Pb^(2+)的吸附率提高了50%,且不受初始浓度的影响。Sepiolite was acidified with hydrochloric acid as a proton donor with the method of ion-exchange, then CTMAB was used to adorn sepiolite in order to obtain organically modified sepiolite. The impacts of adsorption adsorbent dosage, initial pH, adsorption temperature and the initial concentration of solution were discussed. experimental results showed that adsorption of modified sepiolite increased by 50% , was not affected by the concentration of solution.
