摘要
属于硅酸盐类无机矿物材料的黄土构成了位于我国中西部的全球规模最大的黄土高原,近年来,有关黄土材料的研究开始受到关注。介绍了黄土的组成结构和基本性质;总结了几种黄土改性的主要方法,如无机改性、有机改性、高分子改性等;叙述了黄土及其改性产物的应用,尤其是在含重金属离子废水、有机废水及含磷废水中的应用研究进展。认为黄土是一种来源广泛、无毒、廉价易得的天然高分子材料,黄土基水处理剂属于绿色水处理材料,将在水处理领域具有更广阔的应用前景;黄土经一定加工处理后,还可用于环境治理、建筑等领域。
Loess clay （LC） is belonging to silicate based inorganic mineral materials. It constitutes the Loess Plateau in China, which is the biggest loess area in the world. Recently, LC-based materials have been paid more and more attention. In this paper, firstly, the composition, structure and basic property of LC are introduced. Secondly, some methods for modifying LC, such as inorganic, organic, and polymer modification, have been summarized. Thirdly, the application of the modified LC has been reviewed, especially in the treatment of heavy metal wastewater, organic wastewater and phosphorus wastewater. Consider that LC is a kind of non-toxic and cheap natural inorganic polymer materials with extensive sources. LC-based water treatment agent is green water treatment materials, which could be applied in many regions. It can also be applied in other regions, such as environmental management, buildings.
