Removal of color from water using method of ultrasound and fenton

Environmental pollution is rising due to tecnological development and increase of population day by day. Nowadays, dyes are one of the specific pollutants that cause environmental pollution. Dye-containing wastewater when discharge into receiving enviroment by reducing photosynthetic activity in aquatic environment has a negative impact on the transmittace of light. Besides toxtic and carcinogenic effect has occured because of accumulation in aquatic organisms. In this study was conducted with 40 mg/L Reactive Black 5(RB5) dye. Ultrasound (US), Fenton and US/Fenton process on color removal and total organic carbon (TOC) were investigated. Furthermore, the effects of some ions(SO4-2, HCO3- ve NO3-) in water and N2 gas on color removal was analyzed. Finally, 100 mg/L concentration RS5 dye was investigated in order to see the effect of high concentration on the system, color removal efficiencies and TOC values in ultrasound (US), Fenton (Fe+H2O2) and US/Fenton reactions at optimum conditions for 40 mg/L RS5 dyes. As a result of studies, percent of color removal for 40 mg/L concentration of RB5 with Fenton reaction is %91,55; with US/Fenton process is %93,59. Similarly percent of color removal for 100 mg/L concentration of RB5 with Fenton reaction is % 91,50; US/Fenton process is %92,56.
