Abstract
In this paper, the oxidation of dyes from colored textile wastewater by activated carbon (AC)/hydrogen peroxide (H2O2) was investigated. Reactive Red 198 (RR198) and Reactive Black 5 (RB5) were used as model dyes. The surface characteristics of AC were investigated using Fourier transform infrared (FTIR) and scanning electron microscopy (SEM). Dye oxidation by AC/H2O2 was studied using UV-Vis spectrophotometer and Ion chromatography (IC). The effects of AC dosage, initial dye concentration, pH and salt on dye oxidation were investigated. Kinetics analysis indicated that the dye oxidation rates could be approximated at pseudo-second order model. Formate anion was detected as dominant aliphatic intermediate. Results indicated that the AC/H2O2 could be used as an eco-friendly material to degrade dyes from colored wastewater.
