Cr(VI)吸附剂及其吸附机理研究进展

摘要 重金属污染已成为影响人们生活亟亟待解的问题，它不仅威胁着自然环境的持续发展，更是对人类身体健康提出了严峻的考验。其中，六价铬因为环境污染持续久，危害大，更是得到各国研究者的重视。研究者们研究了各种吸附材料，它们对于六价铬的移除能力以及移除机理不尽相同。本文介绍了Cr(VI)吸附材料分类及其特点，重点分析了聚合物吸附材料在吸附和分离Cr(VI)方面的应用进展。并简要介绍了Cr(VI)吸附过程中的吸附动力学模型和等温方程式，以著名的Langmuir和Freundlich模型为例加以说明，为解决重金属铬离子引起的环境污染尤其水污染问题提供一种借鉴。

Cr(VI) adsorption agents and its adsorption mechanism research progress

Abstract Heavy metal pollution has influenced people's life, it not only threatens the sustainable development of the natural environment, but also is a severe challenge to human health. Among them, six chromium because of environmental pollution for long time and the great harm, has been getting more and more attention of researchers in various countries.The researchers studied a variety of adsorption materials, their abilities of the six valence chromium removal and removal mechanism are not the same.This paper introduces the Cr(VI) adsorption materials classification and characteristics, focuses on the analysis of the adsorption of polymer materials in adsorption and separation of Cr(VI )progress on applications. Briefly introduces the Cr(VI) adsorption kinetics models and the isothermal equations of adsorption process, with Langmuir and Freundlich models as the examples. To solve the problem of environmental pollution especially water pollution problem caused by heavy metal chromium ions provides a reference.
