微波镧有机交联改性膨润土吸附磷的研究

用浸泡的方法把制备好的镧改性的膨润土,再用十六烷基三甲基溴化氨表面活性剂进行改性,制备一种新的吸附剂交联有机膨润土应用于除磷研究,其效果比原来的镧改性的无机吸附剂吸附量提高了30%。其最佳制备工艺为:表面活性剂的浸泡浓度为5%,微波功率为166W,微波辐射时间为6m in,溶液的pH为3~4,震荡时间为45m in。磷去除率达到了99%以上,吸附量达到了60mg/g以上,从而为含磷废水的处理提供了一条高效、经济的新途径。

Study on Absorbing Phosphor by Wave Modified La-organo -bentonite

By adding rare earth and organic compound CTMAB to modified la-bentonite with maceration method,modified la-organo-bentonite is produced,which was used to remove phosphor as a kind of absorbent.This new absorbent shows stronger absorption efficiency up 30 percent than that of normal inorganic absorbent.The optimal absorbent manufacture process are based on the following conditions: the maceration concentration of surface active agent is 5 percent,the wave power is 166W,the wave radiation time is 6 minutes,the pH value is 3-4 and the oscillating time is 45 minutes.The removal rate of phosphor can reach 99 percent and the absorption volume is 60mg/g.
