摘要
研究了新生MnO_2对二甲酚橙和亚甲基蓝的脱色效果,考察了影响脱色效果的主要因素。实验结果表明,新生MnO_2对二甲酚橙的脱色效果较好;当二甲酚橙质量浓度为40 mg/L,溶液pH值为5,常温下震荡30min,新生MnO_2的加量为50 mg时,对二甲酚橙的去除率可达95%。新生MnO_2对亚甲基蓝的脱色效果差,最佳条件下的去除率仅为76%。
The decolorizing effects of fresh MnO2 on xylenol orange and methylene blue and the main factors influencing the decolorizing effects were studied. The experimental results showed that fresh MnO2 had good decolorizing effects on xylenol orange, and the removal rate was up to 95 % when the concentration of xylenol orange was 40 mg/L, pH was 5, the amount of fresh MnO2 was 50 mg, and shaking time was 30 min at room temperature. Fresh MnO2 had poor decolorization on methylene blue and the removal rate was only 76 % under the optimum conditions.
