Abstract

Dyes used in various industries are stable, difficult to degrade and carcinogenic in nature. Discharge of effluents containing unexhausted dyes affect aquatic and human chain. Treatment of effluents hence gains utmost priority before its disposal into water streams. In the present study, removal of two acid dyes: Acid Violet 49 (AV49) and Acid Red 88 (AR88) from aqueous solutions using Fenton's process are conducted. Factors influencing dyes removal efficiency were investigated. It was observed that maximum AV49 dye removal efficiency of 98.35 was achieved when solution pH, H2O2, and Fe2+ were 3, 0.005 mol, and 0.0005 mol, respectively for 100 mg/L dye solution. Whereas for 200 mg/L AV49 dye, the maximum dye removal efficiency of 97.25 was obtained with solution pH, H2O2, and Fe2+ were 3, 0.01 mol, and 0.001 mol, respectively. The optimum conditions for 100 mg/L AR88 dye were: solution pH = 3, H2O2 = 0.006 mol, Fe2+ = 0.0005 mol, and dye removal efficiency, 97.30. Similarly, for 200 mg/L, the dye removal efficiency of 96.50 was achieved with solution pH = 3, H2O2 = 0.012 mol, and Fe2+ = 0.001 mol. This study showed high removal efficiency of AV49 and AR88 from aqueous solutions using Fenton's reagents. © 2018 Elsevier Ltd.
