| 摘 要： | 采用十六烷基三甲基溴化铵(CTMAB)制备改性膨润土,重点研究了改性剂的用量、改性时间、改性温度对改性膨润土吸附对硝基苯胺的的影响。同时对膨润土改性前后的吸附性能进行了比较,结果表明,改性膨润土对对硝基苯胺的吸附量明显增加,且吸附等温线符合Langmuir方程。

| Abstract: | Hexadecyltrimethylammonium bromide(CTMAB) surfactants were used to modify bentonite.The consequent was affected by the amount of CTMAB,modifying time and temperature.A comparison of the adsorptive capacity of p-nitroaniline with natural bentonite and modified bentonite was also done,it was found p-nitroaniline adsorption of modified bentonite was higher than that of natural bentonite,the adsorption of p-nitroaniline on modified bentonite agrees well with Langmuir isothermal adsorption equation. |

| Keywords: | bentonite modified p-nitroaniline adsorption |
