摘要
海泡石具有较大的比表面积和优良的吸附性能,而糖类物质及其衍生物分子中含有多种活性基团,直接负载或是经碳化形成的前体材料附着在海泡石表面后,可提供更多可与有机分子结合的位点,从而提高海泡石对各种有机物的吸附性能。为了开辟新的海泡石和糖类物质综合利用途径,以及为有机系海泡石吸附剂复合材料的制备提供新思路,综合评述了海泡石表面改性研究现状、常用于矿物表面改性的糖类物质及其特性、糖类物质改性海泡石复合材料的制备方法及其应用研究进展。在此基础上,提出了糖类物质改性海泡石存在的问题,并指出了未来的研究方向。
Sepiolite has a large specific surface area and excellent adsorption performance.The carbohydrate and its derivative molecules containing a variety of reactive groups directly load on or attach to the surface of sepiolite after carbonization,which provides more sites with which organic molecules are united,so that the adsorption performance of sepiolite to various organic substances is improved.In order to find out a novel way for utilization of the sepiolite and carbohydrates and preparation of absorbing composite materials based on organic sepiolite,the research status of surface modification on sepiolite,the carbohydrate with its properties which are often used for modification on mineral surface,the preparation and application of composite material based on modified sepiolite were reviewed.On this basis,the existing problems of modified sepiolite with carbohydrate were presented and the research orientation was specified.
