| 摘 要： | 选择蒙脱土和高岭土2种典型黏土矿物为吸附体, 通过静态吸附试验研究其对磺胺嘧啶的吸附行为,考察温度和pH值对磺胺嘧啶吸附的影响.结果表明,2种黏土矿物对磺胺嘧啶的吸附等温线均能较好地符合Freundlich和Langmuir吸附方程,且Langmuir方程拟合效果优于Freundlich方程;高岭土对磺胺嘧啶的吸附量大于蒙脱土;温度升高和pH值过高或过低均不利于磺胺嘧啶的吸附.

| Abstract: | A static adsorption experiment on behavior of adsorption of sulfadiazine by montmorillonite and kaolinite was carried out to investigate influence of temperature,and pH on adsorption.Results show that the adsorption isotherms of sulfadiazine on montmorillonite and kaolinite were well described by the Freundlich and Langmuir equations,and the latter is better than the former in fitting.Kaolinite was higher in adsorption capacity than montmorillonite.Adsorption of sulfadiazine decreased with increasing temperature and peaked at pH 8. |
