Activated Carbon Assisted Fenton-like Treatment of Wastewater Containing Acid Red G

The Fenton reaction as an effective advanced oxidation technology has been widely used in wastewater treatment for its stable effluent quality, simple operation, mild condition, and higher organic degradation with non-selectivity. However, the traditional is limited by sluggish regeneration of Fe2+, resulting a slower rate, it necessary to further increase dosage which will production iron sludge. Activated carbon (AC) strong adsorption property, cannot be ignored that also can reduce Fe3+. In this study, acid red G (ARG) adding AC Fe3+/H2O2 system, role reducing ability, reason why Fe3+ were studied. By three kinds ACs, including coconut shell-activated (CSPAC), wood-activated (WPAC), coal-activated (CPAC), ability ACs assist Fenton-like system degrade ARG was clarified. Through final effect Fe3+, type best promotion CSPAC. different influence factors particle size, concentration CSPAC, H2O2, pH value observed. conditions determined CSPAC powder size 75 μm 0.6 g/L, initial H2O2 0.4 mmol/L, 0.1 = 3. observed could accelerate early rate process system. FT-IR XPS confirmed C-O-H group on surface Fe2+. This study improve understanding reaction, promote application sewage treatment.
