吸附法是指利用吸附剂与杂质、色素物质、有毒物质、产品之间分子引力的差异,从而起到分离净化作用方法。水体Cr(VI)污染严重威胁着人类健康和生态系统,Cr(VI)污染防治成为全球性环境问题,含Cr(VI)水处理受到人们的普遍关注。本文简要介绍了吸附法除铬的原理与特点,重点综述了活性炭、天然有机吸附剂、天然无机吸附剂和合成吸附剂去除Cr(VI)的性能、特点和研究进展。提出开发和改性有害入侵植物生物质高效吸附剂和对吸附剂解吸等建议。Adsorption method refers to the use of adsorbent and impurities, pigment substances, toxic substances, product difference between molecular attraction, thus plays the role of separation and purification method. A Cr(VI) pollution in water exerts great risks on human health and ecosystem, and Cr(VI) pollution prevention has been recognized as a globally environmental challenge. Therefore, the removal of Cr(VI) from contaminated water has been brought into focus around the world. In this article, the principle and characteristics of adsorption were briefly introduced, and the performance, the features and the corresponding research advance of various kinds of Cr(VI) adsorbents including active carbon, natural organic adsorbents, natural inorganic adsorbent and synthetic adsorbent were system ically reviewed. The proposed development and modification of the invasion of harmful plant biomass adsorbent and adsorption desorption recommendations.
