Case Study

Electrochemical Degradation of Acid Green 28 Dye

Irikura, Kallyni, et al. Journal of environmental management, 2016, 183, 306-313.

Acid green (AG) 28 is a dark green dye containing anthraquinone chromophores, which is widely used in textile dyeing and plastic coloring. In this study, the statistical response surface methodology (RSM) was used to investigate the effect of different parameters on the electrochemical degradation of acid green (AG) 28 dye in a filter press reactor using Ti/β-PbO2 or Ti-Pt/β-PbO2 anodes. The results showed that the decolorization rate of the dye solution could reach 90% under the optimal experimental conditions after 3 h of electrolysis.
Mechanism of electrode degradation of AG 28 dye
· The degradation pathways of the AG 28 molecule are illustrated during the initial phase of electrolysis, where the sulfonic groups are released through hydrolysis, resulting in a hydrolyzed compound with m/z ¼ 533.
· This compound then breaks down into anthraquinone and aminobenzene derivatives with m/z ¼ 148. The subsequent degradation of these derivatives, primarily by HClO, leads to the creation of a chloramine compound with m/z ¼ 248.
· The chlorination of amino groups is found to be more reactive than that of the aromatic portion. The production of chlorinated compounds was qualitatively confirmed by the measurement of free and total chlorine in the solution post-electrolysis.
· A significant level of organochlorine compounds was observed after subtracting both values, mainly attributed to the formation of chloramines and chloroform as final products.
