摘要
UV -vis/H2 O2 /草酸铁络合物法是一种高级氧化工艺 ,这个工艺产生的羟自由基·OH是一种很强的氧化剂 ,能很快和水中有机物发生反应 .以苯胺为处理对象对该法的氧化能力和效果进行了研究 ,并确定了降解苯胺的最佳工艺条件 :pH =3 .5 ,Fe2 + ∶H2 O2 ∶C2 O2 -4 ≈ 1∶4∶6 (mole) .UV -vis/H2 O2 /草酸铁络合物法处理高浓度苯胺水样非常有效 ,12min内苯胺去除率均在 99%以上 .
The UV-vis/H 2O 2/Ferrioxalate process is an advanced oxidation process.The hydroxyl radical (·OH) generating in this process is a strong oxidant and reacts rapidly with organic compounds in water.Here aniline wastewater was treated by this oxidant.The oxidation behavior and effect was studied.The optimum conditions to remove aniline from wastewater by UV-vis?/?H 2O 2?/?Ferrioxalate process were as follows:pH= 3.5 ,Fe 2+ ∶H 2O 2∶C 2O 4 2- ≈1∶4∶6 (mole).The UV-vis?/?H 2O 2?/?Ferrioxalate process was very efficient for the treatment of water highly contaminated by aniline and the removal efficiency of aniline was more than 99% within 12?min.The disposal of simulated aniline water sample by dynamic process was better than by static process.
