| 摘 要： | 采用电化学法降解含酚废水 ,在隔离阴阳极室的条件下 ,以不同的温度进行电解脱酚实验。结果显示 ,苯酚转化率可高达 95%以上 ,并随温度升高而提高 ;对比实验揭示 ,碱性电解液有利于苯酚的降解。动力学研究表明 ,电解法脱酚遵循准一级反应动力学过程 ,其活化能 Ea=1 2 .75～ 1 6 .0 6 k J· mol- 1,远低于一般反应的活化能 ( 6 0～ 2 50 k J·mol- 1) ,这是电化学脱酚速率快 ,降解彻底的重要原因

| Abstract: | The electrochemical experiments for the degradation of phenol waste water were carried out at different temperatures.The results showed that the phenol degradation efficiency was up to more than 95%,and increased with rising of the temperature.Parallel tests suggested that the alkaline electrolyte was beneficial to phenol degradation.Further study reveals that the electrochemical degradation of phenol follows the one -step reaction dynamics.The obtained energy of activation E a=12.75~16.06kJ·mol -1 ,which is much less than those of common chemical reactions.The result proves the phenol degradation process to be feasible,speedy and complete. |
