摘要
以受污染松花江水为研究对象，用色－质联机（ＧＣ／ＭＳ）为主要检测手段，探讨了高锰酸钾的除微污染效能与机理。结果表明，高锰酸钾在中性条件下具有最佳的除微污染效果，对难氧化的有机污染物也有良好的去除效果。高锰酸钾在反应过程中产生的中间态成分（新生态水合二氧化锰）对去除微污染效率有重要影响，通过吸附与催化作用显著地提高了对水中微量有机污染物的去除效率。
This paper evaluated the effectiveness of permanganate pre-oxidation for removal of organic micropollutants from surface water at various pH by means of GC/MS analysis. Results showed that permanganate pre-oxidation at neutral pH level had the optimal removal officiency for organic micropollutant, and substantially refractory organic pollutants could be removed. It was considered that the hydrated manganese dioxide formed in the process of permanganate pre-oxidation played a very important role in the remoal of orgnic micropollutants by adsorption and catalytic activities.
