摘要: Abstract Degradation of the acid red 97 dye using wet oxidation, by different oxidants, and electro-Fenton systems was investigated in this study. The oxidation effect oxidants such as molecular oxygen, periodate, persulfate, bromate, hydrogen peroxide system compared. Mineralization AR97 with periodate appeared more effective when compared that other at equal initial concentration. When 5 mM used, first minute oxidative treatment, decolorization percentage solution 150 200 °C reached 88 98%, respectively. total organic carbon removal efficiency these temperatures also 60 80%. degradation studied process. optimal current value Fe2+ concentration were found to be 300 mA 0.2 mM, results showed process can lead 70 95% mineralization after 3 5 h giving carboxylic acids inorganic ions final end-products before mineralization. products obtained from identified GC/MS 1,2-naphthalenediol, 1,1′-biphenyl-4-amino-4-ol, 2-naphthalenol diazonium, 2-naphthalenol, 2,3-dihydroxy-1,4-naphthalenedion, phthalic anhydride, 1,2-benzenedicarboxylic acid, phthaldehyde, 3-hydroxy-1,2-benzenedicarboxylic 4-amino-benzoic 2-formyl-benzoic acid.
