    Comparative Study of the Adsorption Aniline on Modified Bentonites

      摘要
    • 摘要: 利用高温焙烧和超声波的物理方式改性膨润土,对水溶液中苯胺的吸附进行系统地研究,考察了改性条件(焙烧温度与超声波功率)和吸附条件(pH与温度)对吸附效果的影响.结果表明:超声波和焙烧改性的膨润土对水溶液中苯胺的吸附率分别为40.61%和38.74%,明显优于未改性的膨润土(30.49%).

       

      Abstract: This paper mainly deals with the method of modifying natural bentonite by baking or ultrasonic wave.Adsorption of the modified bentonite for aniline was investigated.In the study,the effects of baking temperature,ultrasonic power,pH and temperature on the adsorption efficiency were discussed.The results showed that the adsorption rate of modified bentonite by baking and ultrasonic wave was 40.61% and 38.74%,respectively,better than that of raw bentonite(30.49%).
