摘　　要：用Zr2+对膨润土改性,并用改性后的膨润土对大红染料废水进行处理,考察了pH值、反应温度、反应时间、改性膨润土用量等因素对大红染料去除率的影响,研究了其吸附动力学及等温吸附。Zr2＋ was used for preparing modified bentonite, and the modified bentonite was applied for treating red dye wastewater. The effects of pH, temperature, reaction time and the dosage of modified bentonite on the removal rate of red dyeing were investigated. Furthermore, the adsorption kinetics and adsorption isotherm of the process were analyzed.
