摘　　要：以FeS为活化剂,过硫酸钾为氧化剂处理甲基橙模拟废水,耗时较长,且处理效果不佳。通过加入过渡金属离子Cu^(2+)、Ag+、La^(3+)进一步提高该体系的效能。结果发现:Cu^(2+)和Ag+均能强化FeS/过硫酸钾体系降解甲基橙,当n(FeS):n(金属离子)=1:1时,甲基橙去除效果最佳,且Cu^(2+)对该体系的强化作用强于Ag+;低浓度的La^(3+)对该体系降解甲基橙有微弱促进作用,但还有待考察。The treatment of methyl orange stimulated wastewater with FeS as the activator, potassium persulfate as the oxidant takes a long time, and the effect was unsatisfactory. Adding transition metal ions Cu^2＋, Ag＋and La^3＋ to further improve the system efficiency, the results showed that, both Cu^2＋and Ag＋could enhance the degradation performance of FeS/potassium persulfate system on methyl orange, when the n（FeS） ： n（metal ions）was 1 ∶ 1, the removal effect of methyl orange was the best, and the strengthening effect of Cu^2＋on the system was stronger than that of Ag＋. Low concentration La^3＋ had a weak acceleration effect on the degradation of methyl orange by the system, but it remained to be further investigated.
