摘　　要：研究了接触辉光放电等离子体降解水体中的酸性品红.考察了各种影响因素如初始浓度、初始pH值、催化剂对其降解效率的影响.实验结果表明:弱酸性条件(pH=5左右)有利于降解,催化剂存在下可明显加快降解,在加入催化剂Fe2+和Mn2+时降解率达到87.35%和89.57%.Contact glow discharge electrolysis is a novel type of electrochemical process. The degradation of Fuchsin acid in aqueous solution by contact glow discharge electrolysis is investigated. Some influence factors such as initial concentration, initial PH and the catalysts are examined. The results indicate that the weak acid condition is beneficial to degradation, and the catalyst can speed up the degradation obviously. In the presence of Fe62 ＋ and Mn^2 ＋ , the ratios of degradation are 87 35% and 89.57% respectively.
