强化高锰酸钾氧化去除水中有机污染物的技术综述

Review on the catalytic permanganate oxidation of organic pollutants

探讨投加催化剂或与其他技术联合提高高锰酸钾氧化效能的方法,综述了过渡金属、腐殖酸、络合剂、ABTS、二氧化锰和超声等强化高锰酸钾氧化效能的技术,分析每种技术的优势和缺陷,认为后续研究应注重铁基或者其他过渡金属非均相催化剂的开发,既降低催化剂的成本,也实现催化剂的回收利用。

A series of methods to enhance the performance of permanganate oxidation by adding catalysts or coupling with other water treatment processes are discussed. The transition metal ions,humic acid,ligands,ABTS,manganese dioxide and ultrasound were proved to be effective in increasing the oxidation rate of permanganate. The advantages and disadvantages for each method were discussed intensively. The following studies should be focused on developing the heterogeneous catalysts based on iron or other transition metals,to reduce the cost of catalysis and make it convenient to segregate and recycle.
