地表水外源铬价态转换及六价铬污染消除机理探讨

Valence Change of Exogenous Chromium and Mechanism of Decontamination of CrVI in Natural Water

铬污染作为一种常见的重金属污染已引起全球的重视。对自然水体中铬形态及污染消除机理进行深入探究,是了解六价铬污染及寻求六价铬污染防治方法的关键。文章通过理论研究及相关研究文献的综述,对外源性三价铬、六价铬的主要存在形态、相互转化及六价铬污染消除机理等作了深入的探讨。

As a common pollution of heavy metal contamination, chromium pollution is a great concern all around the world. Intensive studies of the existing form and mechanism of decontamination of chromium are the keys of knowing about chromium pollution and seeking the optimal methods for controlling. In this paper, existing form, transformation of exogenous CrIIl and CrVI and the mechanism of decontamination of CrVI in natural water are discussed.
