接触辉光放电等离子体降解水体中的邻氯苯酚

Degradation of o-chlorophenol in aqueous solution by contact glow discharge electrolysis

接触辉光放电电解是一种新型的产生等离子体的电化学方法。本文测定了催化剂、pH 值对接触辉光放电等离子体降解水体中邻氯苯酚降解效率的影响;并利用高效液相色谱检测了中间产物和邻氯苯酚降解浓度随时间的变化。实验表明:碱性条件下降解有利,Fe2+催化作用下降解效率明显提高。

Contact glow discharge electrolysis is a novel type of electrochemical process. Effects of catalyst and pH value on the degradation of o-chlorophenol in aqueous solution with contact glow discharge electrolysis plasma were studied. The experimental data showed that degradation benefits from basic condition, Fe2+ had a remarkable catalytic effect on degradation. The concentration of intermediate products and o-chlorophen 01 changed by time were analyzed by a high performance liquid chromatograph (HPLC).
