用高锰酸钾预处理饮用水会导致THM前体氧化。此外，高锰酸盐还原产生的二氧化锰沉淀物可以吸附THM前体。讨论了氯化和二氧化锰吸附研究。总有机碳、富里酸、艾氏腐殖酸，以及钙对二氧化锰吸附的影响也包括在内。包括15个参考文献、图表。

Pretreatment of drinking water with potassium permanganate can result in the oxidation of THM precursors. Additionally, the manganese dioxide precipitate that is generated by the reduction of permanganate can adsorb THM precursors. Chlorination and manganese dioxide adsorption studies are discussed. Total organic carbon, fulvic acid, Aldrich humic acid, and the influence of calcium on manganese dioxide adsorption are also covered. Includes 15 references, figures.
