The Electrochemical Regeneration Mechanism of Activated Carbon by Electrochemical Method

通过研究ｐＨ值对苯酚在活性炭上的吸附平衡的影响，活性炭在不同电极上的电化学再生效率和循环再生对活性炭再生效率的影响，结合以前的有关研究结果分析认为活性炭的电化学再生过程机理中包括电脱附，ＮａＯＨ 碱再生，ＮａＣｌＯ 化学氧化等过程．实验结果表明，电化学再生活性炭具有较高的再生效率．The adsorption equilibrium of phenol on activated carbon was tested. The electrochemical regeneration of activated carbon adsorbing phenol was studied in different electrodes and different regeneration cycle times. The experimental results show that the electrochemical regeneration is a good method with good regeneration coefficiency for the regeneration of activated carbon. In the electrochemical regeneration process, phenol was first desorbed from the activated carbon, then was oxidated by the strong oxidants produced in the electrolysis.国家自然科学基金!（29676035
