以高比表面改性煤系高岭土为吸附剂，分析了吸附时间、吸附剂用量、pH 和染料初始浓度等因素对改性煤系高岭土吸附次甲基蓝染料的影响，并对改性煤系高岭土的再生效果进行了研究.静态吸附结果表明：改性煤系高岭土的用量为0.2 g；pH 为6.012时，改性煤系高岭土对次甲基蓝有较好的吸附；吸附时间取30 min 为宜.改性煤系高岭土对次甲基蓝的吸附等温线拟合结果表明，该吸附过程符合 Langmuir 吸附等温式，属于单分子层吸附，改性煤系高岭土对次甲基蓝的吸附符合拟二级动力学方程.

Activated coal-bearing kaolinite with large surface area was used as an adsorbent for the removal of methylene blue from wastewater,and the effects of some factors including adsorption time,the dosage of coal-bearing kaolinite,solution pH and initial concentration of dye on the adsorption of methylene blue were investigated.Furthermore,the regeneration of the activated coal-bearing kaolinite after adsorp-tion was studied.Static adsorption showed that the best dosage of activated coal bearing kaolinite was 0.2 g,when the pH value was between 6.0 - 12,methylene blue could be adequately adsorbed by the activated coal-bearing kaolinite,the best adsorption time was 30 min.The fitting of experimental data showed that the adsorption process of activated coal-bearing kaolinite for methylene blue was consistent with Langmuir isotherm formula,showing that the adsorption was mono molecule layer adsorption.The adsorption kinetics of methylene blue on the activated coal-bearing kaolinite followed the pseudo-second-order kinetic equation.
