摘　　要：以甲基橙为目标污染物,研究了常温下羟胺强化Fe S活化过硫酸钾对甲基橙的降解效果。分析了投加量、p H值、反应时间等因素对甲基橙降解效果的影响。当甲基橙初始浓度为100mg·L^(-1),羟胺与Fe S组合投加量为0.9mmol·L^(-1),p H值为7,反应时间为20min时,甲基橙去除效率最高,达到90.38%。研究结果表明:羟胺能够加快Fe S活化过硫酸钾速度,提高降解效果。The degradation effect of hydroxylamine FeS activated potassium persulfate on methyl orange at nor- mal temperature was studied with methyl orange as the target pollutant.The effects of adding amount,pH value and reaction time on the degradation of methyl orange were analyzed.When the initial concentration of methyl orange is 100mg@L-1,the combined dosage of hydroxylamine and FeS is 0.9mmol-L ^-1,pH value is 7,reaction time is 20min, the removal efficiency of methyl orange is the highest,reaching 90.38%.The results show that hydroxylamine can accelerate the FeS activation of potassium persulfate and improve the degradation effect.
