Decomposition of pollutants in textile wastewater during the Fenton process in the presence of iron nanocompounds

The efficiency of the decomposition of pollutants in textile wastewater has been determined by the Fenton method in the presence of iron nanocompounds and the results have been compared with those by the classical Fenton method. The wastewater was purified with ferrous sulfate and ferrous sulfate with the addition of iron(II, III) nanocompound. The effect of optimization of the process was examined by adding various amounts of ferrous sulfate and iron(II, III) nano-oxide, hydrogen peroxide and changing pH of the solution. It was found that addition of iron nano-oxide in the presence of ferrous sulfate increased the efficiency of pollutant decomposition in the wastewater.
