dc.description.abstract | In this study we investigate the effect of acetone on the batch photolytic degradation at 253.7 nm of chlorazol black (CB) azo dye in different matrices basically deionized water and mineral water. It was found that acetone (50 mM) assisted-UV treatment of CB (20 mg/L) resulted in 5.6-fold increase in the initial degradation rate, as compared with UV alone for both systems. Radical scavenger tests using oxygen saturation have showed that methyl radical was probably the main species responsible for the efficient degradation of CB in UV/acetone system . The obtained results show that CB degradation is also effective in mineral water. For both matrices, the initial amount of CB was nearly removed after about 30 min, but the degradation rate proceeds much quickly in deionized water... | en_US |
