活性碳纤维对苯胺的吸附性能研究

The research on adsorption characteristics of activated carbon fiber to aniline solution

采用静态吸附法探究活性碳纤维对苯胺溶液的吸附能力,探讨了在不同的吸附时间、不同质量的活性碳纤维、不同初始浓度的苯胺溶液和不同p H值、盐效应、温度等条件下对吸附效率的影响,同时探讨了颗粒活性炭对苯胺溶液的吸附能力。研究结果表明,活性碳纤维对苯胺溶液具有良好的吸附效果,即使在常温下,活性碳纤维对苯胺都具有较高的吸附效率,而盐的质量分数也会提高其吸附效率,对实际应用有参考价值;相同质量的颗粒活性炭对苯胺溶液的吸附效果不及活性碳纤维。

The adsorption capacity of activated carbon fiber to aniline solution through static adsorption method was discussed in this paper. The influence of adsorption time, dose of activated carbon fiber, initial concentration of aniline solution, p H value, salt effect and temperature on the adsorption were investigated. Moreover, the paper also studied the adsorption capacity of activated carbon particles to aniline solution. The results shown that activated carbon fiber was a good adsorbent for aniline solution with a high adsorption efficiency even at normal temperature. Besides, salt content can improve the efficiency. This conclusion has reference for practical application. The adsorption effect of activated carbon particles to aniline solution is not as good as that of activated carbon fiber at the same dose.
