RESEARCH ON PHOTO DEGRADATION OF ANILINE WASTEWATER BY DYNAMIC UV-vis/H_2O_2/ FERRIOXALATE COMPLEXES PROCESS
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.
