| 摘 要： | 用硫酸铜、高锰酸钾、硫酸亚铁、氢氧化钾、柠檬酸、硝酸铜、乙酸铅、硝酸等溶液浸渍处理活性炭纤维,考察了改性活性炭纤维对废水中苯酚的吸附性能。结果表明,用硫酸铜溶液改性的活性炭纤维对苯酚的吸附性能强于未改性的活性炭纤维,经高锰酸钾、硫酸亚铁、氢氧化钾、柠檬酸、硝酸铜、乙酸铅、硝酸等溶液改性的活性炭纤维对苯酚的吸附能力下降。浓度为0.05%~1%的硫酸铜溶液对0.2 g活性炭纤维进行改性的效果优于其它浓度的硫酸铜溶液。活性炭纤维上负载的铜离子过多会降低活性炭纤维对苯酚的吸附量。

| Abstract: | Activated carbon fiber(ACF) was treated by impregnating with solutions of cupric sulfate,potassium permanganate,ferrous sulfate,potassium hydroxide,citric acid,cupric nitrate,lead acetate and nitric acid and etc.Phenol adsorption properties of ACF modified with different solutions were studied.The results show that phenol adsorption property of ACF modified with cupric sulfate is better than that of ACF not being modified,while phenol adsorption properties of ACF modified with potassium permanganate,ferrous sulfate,potassium hydroxide,citric acid,cupric nitrate,lead acetate and nitric acid have dropped.Modification effect with cupric sulfate of which the concentration is 0.05%~1% is superior to modification effect with other concentrations of cupric sulfate solution when 0.2 g ACF is used to treat waste water containing phenol.The excessive loading of cupric ion on ACF can decrease phenol adsorption capacity. |
