摘　　要：研究了影响高锰酸钾对染料废水脱色的有关因素,结果表明,脱色反应的最佳pH值应小于1.5,高锰酸钾的浓度对脱色效果影响显著.通过对12种不同模拟染料废水,包括活性染料、酸性染料、直接染料和阳离子染料脱色效果的比较,探知高锰酸钾对大多数染料的脱色效果均十分显著.总有机碳的测定结果表明,高锰酸钾虽能较好地去除染料废水的色度,但对有机物的降解不彻底.The decolorization of dye wastewater with potassium permanganate was studied. The results are that the best pH value for decolorization is below 1. 5 and the concentration of potassium permanganate has significant effect on decolorization. Twelve kinds of simulated dye wastewater, separately prepared with reactive, acidic, direct and cationic dyes, were decolorized. The result shows that potassium permanganate has obvious effect of decolorization on the most of dye wastewater. The result of total organic carbon shows that potassium permanganate can't degrade dye wastewater completely.
