Iron Oxide Particles Loaded Activated Carbon Cloth and Comparison of Adsorption and Fenton Reaction for Efficient Cationic and Anionic Dyes Removal

This paper illustrates an experimental study on the elimination of Remazol Brilliant Blue R (RBBR) and Basic Red 18 (BR 18) dyes from synthetic aqueous solutions with iron oxide particles activated carbon cloth (IACC). The most important objectives of the experimental tests were to investigate the impacts of the different operating parameters, such as solution pH, adsorbent amount, H2O2 concentration and initial dye concentration on both studied colors removal. The experimental results demonstrated that 96.14% RBBR dye and 98.44% BR18 dye removals were observed for initial dye concentration of 100 mg/L with adsorbent amount of 1.0 cm(2)/100 mL, H2O2 concentration of 2.5 mu L/L and optimum pH at the end of 60 min of operation. It was observed that, an increase in initial dye concentration decreased the dye removal efficiency. Optimum pH for the highest RBBR dye removal was 2.5 and 3.0 for BR 18 maximum removal efficiency. It was also observed that the increase in hydrogen peroxide (H2O2) concentration in the solution reduces the dyes removal efficiency. The loaded iron oxide particles on carbon cloth catalyst revealed to be an effective solution for high removal performance of cationic and anionic dyes.
