摘要：

Degradation of Acid Red I (ARI) dye by electrochemical treatment and UV light irradiation was studied in this work. The effect of the current density and the concentration of NaCl and dye on the decoloration and degradation efficiency were studied and optimized. The UV irradiation was monitored by UV-Vis spectrophotometry and chemical oxygen demand. The kinetic constants for decoloration and degradation were calculated. Degradation of 86% was achieved in 160 min and the first-order kinetic constant was 0.013 min(-1). Degradation products were identified by gas chromatography/mass spectrometry. The mechanism for the degradation of ARI was proposed.
