摘　　要：高铁酸盐(Ⅵ)具有高效降解水中重金属、有机污染物的优势,但水体中广泛存在的腐殖酸因其大量的活性官能团会干扰高铁酸盐对水中污染物的降解去除。系统概述了高铁酸盐在降解不同重金属、新兴污染物的过程中,因腐殖酸的加入呈现出不同的影响效果,并对其影响机制进行了归纳总结。展望了在实际水样中多种污染物共存的体系下,腐殖酸产生影响的先后顺序以及对复合机制的探讨。Ferrate(Ⅵ)has the advantage of efficient degradation of heavy metals and organic pollutants in water,but humic acid widely existing in water will interfere with the degradation and removal of pollutants by ferrate in water due to its large number of active functional groups.This paper systematically summarized the different effects of ferrate on the degradation of different heavy metals and new pollutants due to the addition of humic acid,and summarized the influencing mechanism.The sequence o£the influence of humic acid and the discussion of the compound mechanism under the coexistence o£many kinds of pollutants in actual water samples were prospected.
