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.
