| 摘 要： | 采用固相微萃取-气相色谱法,考察活性炭纤维电助吸附水中有机污染物(苯酚、苯胺、硝基苯等)的行为,以及吸附时间、电压、电解质等不同参数对吸附的影响。结果表明,不同取代基的苯衍生物电吸附改变量不相同。与开路电压相比,正极化下活性炭对苯酚的吸附更好,而负极化对苯胺的吸附效果更佳,正负极化对硝基苯的影响大致相等。在加入硫酸钠电解质后,吸附量和吸附速率都有所增加。该方法可降低吸附工艺成本,使吸附处理更加经济有效。

| Abstract: | The electro-assistant solid-phase microextraction-gas chromatography was used to adsorpt phenol,aniline and nitrobenzene in water,and the extraction conditions of the adsorption were optimized.The results showed that the enhancement for electro-asorption changes with different groups substituting,the amount of electro-adsorption changes is different.Compared with open circuit voltage,under anodic polarization adsorption of activated carbon is better for phenol,and under cathode polarization adsorption of aniline is better for phenol,anodic and cathode polarization impacts on nitrobenzene is equal.The adsorption capacity and adsorption rate are increased after adding sodium sulfate in the electrolyte.This method can reduce the cost of the adsorption process and make adsorption more economical and effective. |
