摘　　要：在室温25℃,染料氨基黑10B质量浓度为40 mg/L,FeSO4浓度为2 mmol/L,H2O2浓度为4.5 mmol/L,pH值为3.0,反应时间为60 min条件下,对比研究了5种常见无机离子(Fe3+,Cu2+,NO3-,H2PO4-和Cl-)对Fenton氧化染料氨基黑10B脱色效果的影响。试验结果表明,Fe3+具有一定的促进作用,而Cu2+,NO3-和Cl-则对反应有一定的抑制作用,溶液中H2PO4-的存在,对Fenton有较强的抑制作用。Under the conditions of temperature 25 ℃, 40 mg/L dye Amido Black 10B, 2 mmol FeSO4, 4.5 mmol H2O2, pH 3.0, and reation time 60 min, the effects of the five kinds of inorganic ions, as Fe3＋, Cu2＋, NO3-, H2PO4- and Cl-, on the treatment for Amido Black 10B by Fenton oxidation were compared and analyzed. The results showed that Fe3＋ acted a certain role in promotion, while Cu2＋, NO3-, and Cl- would act as inhibitors in some extent, and H2PO4- had significant inhibition on the oxidation procession.
