中文摘要：

功能化有序介孔二氧化硅材料具有均一可调的介孔孔径、规则的孔道、稳定的骨架结构、易于修饰的内表面和较高的比表面积、高的吸附容量等特性,可用于生物、医药、环境样品等复杂基体中痕量分析物的高选择性分离与富集,因此在样品前处理中的应用特别引人瞩目。简要介绍了功能化有序介孔二氧化硅材料的制备方法,综述了功能化有序介孔二氧化硅材料在分离富集金属离子、有机污染物以及生物大分子样品前处理中的应用进展。

英文摘要：

Functionalized ordered mesoporous sillica materials have uniform and adjustable pore diameters,regular pore channels,stable skeleton structures,easily modified inner surfaces,relative high specific surface area and high adsorption capacity,etc.They can be used for selective separation and enrichment of trace analytes in complicated samples of biology,medicine and environment.Thus,functionalized Ordered Mesoporous Sillica Materials are gained special attention for sample pretreatment application.This review gives an introduction to preparation of functionalized mesoporous silica materials and an overview of their applications on separation and enrichment of mental ions,sample pretreatments for organic pollutants and biomacromolecules.
