Degradation of Azo Dye Acid Orange 7(AO7) by Heat, ZVI and Heat/ZVI Activated Persulfate
|
Abstract:
Effects of temperatures,PS concentrations and ZVI dosages on AO7 decomposition were investigated in sole heat and ZVI activating systems.The degradation results of two systems were compared for selecting a better activating way for AO7 degradation and finally the two activating ways were combined for getting the optimal AO7 degradation efficiency.The degradation of AO7 by Heat/PS systems followed pseudo first-order kinetics.The reaction rates increased with increasing reaction temperatures(elevated from roo...
