对无机离子影响Fenton试剂的催化氧化性能进行了研究,不同的无机离子对Fenton试剂降解苯胺的性能具有不同的促进或抑制作用.实验结果表明:Fe(Ⅲ)对Fenton试剂催化降解苯胺具有明显的增强促进作用;磷酸根、Cu(Ⅱ)、氯离子和碳酸根等对催化降解性能有不同的抑制作用,其抑制能力的大小为:H2PO4->Cl->Cu2+>碳酸根;而SO42-、NO3-、NH4+却对Fenton试剂无干扰作用.初步探讨了这些无机离子对Fenton试剂影响作用的机理.

In this paper, the effect of some inorganic ions on the degradation of aniline with Fenton’s reagent was studied. Experimental results showed that ferric ions can enhance the catalytic oxidization ability of Fenton’s reagent. Phosphate, chloride ions, copper ions and bicarbonate ions will suppress the catalytic oxidization ability, and the inhibition ability was: H2PO4-> Cl-> Cu2+> HCO3-. For the ions of sulfate radical, nitrate radical and ammonium, the effect of these ions on the Fenton’s system catalytic ability was not found. On the other hand, the mechanism of inhibition action of these inorganic ions was discussed.
