| 摘 要： | 采用自制电化学反应器对模拟对氯苯酚(4-CP)废水进行了电化学氧化降解的研究,考察了支持电解质的浓度、外加电压、pH值、对氯苯酚初始浓度及NaCl电解质等对4-CP降解的影响,得出了对氯苯酚的电化学氧化降解是符合准一级反应动力学模型,且反应速率常数主要受外加电压的影响,与外加电压的2.6次方成线性关系,当NaCl为电解质时,以间接反应为主,反应速率常数可提高一个数量级.

| Abstract: | In this paper,using a cylinder electrical chemical reactor,through static experiment,a series of related factor including the concentration of supporting electrolytes,initial p-chlorphenol concentration,pH value,the concentration of supporting electrolytes,etc,was studied.The results showed that the electrical chemical process is better for the degradation and the apparent reaction rate is first-order.And the reaction rate constant has linear relationship with the 2.6th power of applied voltage and negative the 0.24th power of initial concentration of 4-CP.When using NaCl as supporting electrolytes,the reaction rate constant can be enhanced one order at least. |
