摘　　要：采用振荡吸附法,以膨润土为原料,测定了膨润土对NBPT的吸附容量,并考察了NBPT的初始浓度和处理温度对膨润土吸附NBPT效果的影响。结果表明:在30℃下,固液比为50g/L时,膨润土对NBPT的吸附容量可达8.34mg/g,随着初始浓度的增大,吸附量也随之增大。The absorption behaviors of bentonite on NBPT were evaluated with a batch adsorption method. The effects of liquid--solid ratioand initial concentration of NBPT were investigated. The results showed that the absorption ca- pacity of bentonite on NBPT could reach 8.34 mg/g when the liquid--solid ratiowas 50 g/L and the absorbed amount increased with the increase of initial concentration of NBPT at 30 ℃.
