| 摘 要： | 三氯乙烯（TCE）是污染土壤和地下水中检出率较高的氯代有机物。以TCE为研究对象，考察了地下水无机成分和腐殖酸对高锰酸钾氧化TCE的影响，研究了不同离子强度下的MnO，颗粒行为，并测定了泥浆系统中TCE的氧化效果，结果表明：当TCE初始浓度为20mg／L、高锰酸钾与TCE的摩尔比为2：1，离子浓度〈0．1mol／L时，TCE去除率可达98％以上，Na^＋、Cl^-、HCO3-对TCE的去除率影响甚微，但离子强度对MnO2的沉淀生成影响显著；0．1mol／L的K^＋对TCE的去除有一定程度的抑制；0．1mmol／L的Fe^2＋和腐殖酸对TCE的氧化有显著负面影响。泥浆系统实验进一步验证了有机质对高锰酸钾氧化TCE的影响很大。
