| 摘 要： | 研究十六烷基三甲基溴化铵(CTMAB)有机改性沸石对水中2种典型多环芳烃(PAHs)菲、蒽的吸附性能。结果表明,Langmuir和Freundlich等温吸附方程均可以很好地描述有机改性沸石对菲、蒽的吸附行为;菲、蒽在有机改性沸石上的吸附主要受温度的影响,吸附随温度的上升而减少,说明吸附是放热行为。

| Abstract: | The zeolite was modified with?cetyltrimethylammonium bromide(CTMAB) and its adsorption properties to phenanthrene and anthracene in water was also studied.The results showed that the adsorption isotherms could be described by Langmuir and Freundlich models.The adsorption of 2 PAHs was mainly affected by temperature,the increase of temperature might reduce the adsorption of PAHs,which indicated that the adsorption was exothermic. |
