摘要

水污染问题已在全球范围内引起极大关注。然而，水体中污染物种类繁多、稳定性强且难降解，用传统处理方法如物理絮凝、自然沉降和过滤等，已难以高效、完全去除水中污染物。近年来，吸附法由于具有高效、低成本、易于操作、吸附剂易得等优势备受青睐。凹凸棒石是一种具有层链状结构和纳米棒状晶体形态的天然含水富镁铝硅酸盐黏土矿物，具有较大的比表面积、丰富的纳米孔道和活性表面基团，因而表现出优异的吸附特性，同时兼有低成本、安全和环保等优势，作为天然吸附材料在环境修复领域展现出巨大应用前景。本文综述了凹凸棒石功能化改性及其在污染物吸附研究方面的最新研究进展。

Abstract

The problem of water pollution has aroused great concern on a global scale. However

there are many kinds of pollutants in water with strong stability and being hard to be degraded. It is difficult to remove pollutants efficiently and completely by traditional methods such as physical flocculation

natural sedimentation

and filtration. In recent years

the adsorption method has been favored due to its advantages of high efficiency

low cost

easy operation

and easy availability of adsorbents. Attapulgite is a natural hydrous magnesium-rich aluminosilicate clay mineral with a layer-chain structure and a nanorod-like crystal morphology. Attapulgite has a large specific surface area

abundant nanochannels

and active surface groups

thus exhibiting excellent adsorption characteristics

combined with advantages of low cost

safety and environmental protection. As natural adsorbent materials

attapulgite shows great application prospects in the field of environmental remediation. In this paper

recent advances in functionalization of attapulgite and its application in adsorption of pollutants and adsorption mechanism are summarized and reviewed.
