| 摘 要： | 研究了各种水溶性阴离子染料在新生态MnO2表面的脱色作用。结果表明，9种不同模拟染料废水(包括直接染料、酸性媒介染料、活性染料)的脱色效果均十分显著．且脱色过程受pH的影响较大。另外。通过CHN元素分析、差热分析、紫外光谱及滴定分析等测试手段．初步认为在酸性介质下．新生MnO2质子化的表面可以吸附阴离子型染料，从而将其去除。

| Abstract: | Wastewater containing different kinds of soluble dyestuffs including direct, acid mordant or reactive dyes are used to study the behavior of fresh MnO-2 in decolorization process.The experimental results show that efficiency of decolorization is rather high.The mechanism is considered due to interface adsorption. ; |
