摘　　要：以苯酚为模型化合物,对比了5种不同的无机还原剂和2种有机成分对高锰酸钾氧化苯酚的影响,考察了无机还原剂和有机成分组合时高锰酸钾氧化苯酚的效能。实验结果表明,亚硫酸根、硫代硫酸根和锰离子促进了苯酚的氧化,苯酚去除率提高了7%～13%;亚铁和亚硝酸根对氧化苯酚表现出先抑制后促进作用,苯酚去除率分别提高了8%和24%;卡马西平(CMZ)和双酚A(BPA)对苯酚的去除率分别提高了7%和16%。当以亚铁、亚硝酸根分别与BPA组合为背景成分时,表现出协同效应,对苯酚去除率分别高达79%和99%。还原剂对高锰酸钾氧化苯酚的影响主要取决于反应中二氧化锰的产生速率和产生浓度。The effects of five inorganic reductants and two organic compounds on the oxidation of phenol by potassium permanganate were compared. The joint effect of combination an inorganic reducing agent and organic ingredient on the oxidation of phenol were also investigated. The experimental results show that sulfite, thiosulfate and manganese ion improved oxidation of phenol with the removal efficiency increased by 7 - 13% , while ferrous ion and nitrite exhibited inhibition first and then improvement of the reaction. The removal efficiencies of phenol increased by 8% and 24% for ferrous and nitrite, respectively. Carbamazepine （CMZ） and bisphenol A （BPA） on the promotion of potassium permanganate oxidation of phenol were 7% and 16%, respectively. Ferrous or nitrite together with BPA, showed synergistic effects on oxidation of phenol, the removal rates of phenol reached 79% and 99% , respectively. The effect of reductants on oxidation of phenol mainly depends on the production rate and concentration of manganese dioxide.
