摘　　要：基于海泡石强大比表面积和离子交换能力,采取一种复合海泡石改性方法,即海泡石活化-盐酸-氯化锰改性,得到酸锰改性海泡石,主要目的是增加海泡石比表面积,增强其吸附性能,并对其理化性质进行研究。结果表明,酸锰改性海泡石比原海泡石比表面积增大了3.75倍,吸附性能提高了3.54倍,性能更加优越。Based on powerful specific surface area and ion exchange capacity of sepiolite,a kind of composite modification method for sepiolite,namely sepiolite activation-hydrochloric acid-manganese modification was adopted,an acid-manganese-modified sepiolite was obtained.The main objective was to increase the specific surface area of sepiolite and enhance its adsorption performance.The physical and chemical properties of the modified sepiolite were also studied.Results showed that the specific surface area of acid-manganese-modified sepiolite increased 3.75 times than the specific surface area of original sepiolite,and the adsorption increased 3.54 times than the original sepiolite.So its function was more superior.
