The degradation of Reactive Red 6B (RR6B) wastewater was treated by Fenton oxidation using on-line spectrophotometric monitoring technology. The ratio of peroxide hydroxide concentration and ferrous ion dosage (HF) was investigated. Dyeing degradation process followed first order kinetics and Behnajady - Modirshahla-Ghanbery kinetics because of above 0.98 R2. Fenton process transient reaction rate and instant hydroxyl radical concentration was calculated. The optimum HF was 143 with 98% dye removal, 0.05mol/(L·s) instant transient reaction rate and 2.4×10-11mol/L initial hydroxyl radical concentration.Keywords

The kinetics of Fenton degradation of azo dye Acid Yellow G by online spectrometry technology was studied in this research. The main influential parameters of Fenton process such as FeSO4 dosage, H2O2 dosage, reaction temperature and pH were investigated and the optimum conditions were 20mg/L FeSO4, 50mg/L H2O2, pH=3 and 38°C. Degradation kinetics analyses of acid yellow G were carried out for superior interpretation of Fenton process and the result indicated that the Behnajady-Modirshahla-Ghanbery (B-M-G) model is more applicable than the first or second order kinetics.Keywords
