| 摘 要： | 采用树脂负载零价纳米铁（NZVI-resin）作为铁源,活化过硫酸钠,产生硫酸根自由基氧化降解偶氮染料甲基橙。考察了温度、NZVI-resin加入量、pH值及过硫酸钠的浓度等因素对甲基橙降解率的影响,并对其降解动力学规律作了初步探讨。结果表明：降解反应遵循准一级反应动力学,在pH=3.0、Fe0=0.2 g.L-1、Na2S2O8=1.33 g.L-1的条件下,30 mg.L-1的甲基橙溶液降解率为99.7%。

| Abstract: | The article adopted the resin with nano zero-valent iron complex（NZVI-resin） as a source of iron to activate sodium persulfate and generate sulfate free radical which may oxidize degradation of methyl orange azo dye.The effects of temperature,the dosages of NZVI-resin,pH,the concentration of sodium persulfa te on methyl orange degradation were also examined.In addition,its degradation kinetics was discussed.The results showed that the degradation of methyl orange followed the first order kinetics.And in the initial pH=3,Fe0=0.2 g.L-1,Na2S2O8=1.33 g.L-1,the degradation efficiency of methyl orange solution with a concentration of 30 mg.L-1could reach 99.7%. |
