摘要
通过测定甲基橙降解的最终产物SO4 2 - 的浓度 ,研究了溶液的 pH值、初始浓度、TiO2 投加量几个条件对光催化降解甲基橙矿化速率的影响 ,并与脱色速率进行了比较 ,结果表明 :光催化降解甲基橙的矿化速率低于脱色速率。
The factors affecting studied on mineralization rate include solution pH value, initial concentration of methyl orange, dose of TiO_2. The investigation is based on measuring ions of sulfate which is the end product of the degradation. It is showed that mineralization rate is lower than that of decolorization of methyl orange.
