摘要
研究了MnO2负载蒙脱土对溴百里香酚蓝的吸附脱色性能，绻果表明：蒙脱土可以改善MnO2在吸附过程中的分散性，提高吸附能力。试验表明该吸附过程符合Lagergren二级速率动力学方程，当MnO2负载蒙脱土用量为1．0g，pH较低，质量浓度10～50mg／L时，较短时间内就仃很好的脱色效果，脱色率可达96．44％。
Study MnO2 loaded montmorillonite adsorption decolorization performed on bromothmol blue. Results showed that： the montmorillonite could improve the dispersion and capacity of MnO2 adsorption process. Tests showed that the adsorption process meets Lagergren second-order rate kinetic equation, when use MnO2 loaded montmorillonite 1.0 g, lower pH, concentration of 10-50 rag/L, a relatively short period of time there is a very good bleaching effect, the decolorization rate up to 96.44 %.
