Sažetak
The chemical degradation of synthetic azo dyes C.I. Acid Orange 7, C.I. Direct Orange 39 and C.I. Mordant Yellow 10 has been studied by the following Advanced Oxidation Processes (AOPs): Fenton, Fenton "like", Ozonation, Peroxone without or with addition of solid particles, zeolites HY and NH4ZSM5. Spectrophotometric (UV/VIS) and total organic carbon (TOC) measurements were used for determination of process efficiency and reaction kinetics. The degradation rates are evaluated by determining their “ pseudo” first-order rate constants. The different hydroxyl radical generation processes were comparatively studied and the most efficient experimental conditions for the degradation of organic azo dyes solutions were determined.
