苯酚在活性炭上的吸附与脱附研究

Abstract

本文研究了苯酚水溶液在活性碳上的吸附平衡关系，溶液PH值对活性炭吸附性能的影响，苯酚在固定床上的吸附动力学和脱附动力学。同时采用间歇法和固定床连续法研究吸附苯酚后的活性炭碱再生工艺过程，多次再生对活性炭再生效率的影响，探讨了碱法再生活性炭的初步规律。

Adsorption equilibrium of phenol in activated carbon and the influence of pH on adsorption equilibrium were measured.The adsorption and desorption dynamics of phenol on activated carbon has been studied.The spent activated carbon with phenol can be regenerated by chemical regeneration with good regeneration efficiency.With the increase of regeneration cycle times,the regeneration efficiency would decrease a little.
