| 摘 要： | 研究多壁碳纳米管(MWNTs)对水中有机物间苯二酚的吸附。分别讨论了不同的吸附参数(如温度、时间、pH)条件下,碳纳米管对间苯二酚吸附量的变化情况,并采用Langmuir和Freundlich模型对MWNTs的吸附等温线进行拟合。结果表明:MWNTs的吸附平衡时间为1h;MWNTs吸附是一个自发的放热过程,低温对其吸附有利;当溶液的pH值在4附近时,MWNTs对间苯二酚的吸附量达到最大;MWNTs对间苯二酚的吸附符合Freundlich和Langmuir等温模型。

| Abstract: | The multi-walled carbon nanotubes （MWNTs） were used as adsorbent to remove 1,3-benzenediol from water. The influence of variation of time, temperature and pH on the adsorption quantity of 1,3-benzenediol in water was analyzed. The adsorption of MWNTs was fitted separately utilizing Langmuir and Freundlieh models. The results showed that the adsorption balance time of MWNTs was 1 hour; the adsorption of MWNTs was spontaneous and heat released, hypothermia was beneficial to adsorption; when the pH was around 4, the adsorption quantity reached the top. The experimental data fit Langrnuir isotherm model better than Freundlieh one. |
