THE APPLICATION OF Fe0/H2O2 FOR COLOR REMOVAL

The decolorization of C.I. Reactive Orange 36 (RO 36) by using Fenton-like process (Fe(0)/H(2)O(2)) was studied. Batch experiments were carried out for investigation of optimum operational conditions such as pH, H(2)O(2) and Fe(0) (iron powder) dosages. The results show that Fenton-like process is an efficient process to remove color from synthetic textile wastewater including RO 36 and polyvynil alcohol (PVA). The optimal conditions were experimentally determined and it was found to be initial pH = 3, [H(2)O(2)] = 50 mg/L, [Fe(0)] = 50 mg/L for [RO 361 = 50 mg/L at room temperature. Under optimal conditions, 94.4% degradation efficiency of dye in aqueous solution was achieved after 60 min of reaction.
