Abstract

The textile dyes Reactive Black (RB5) and Basic Yellow 28 (BY28) were individually exposed to electrochemical treatment in 0.1 M KOH and in phosphate buffer solution pH 5.1, respectively. The cathodic decolorization of the azo dye RB5 was carried out using a Ni-polyvinylchloride composite. The methine dye BY28 was anodically treated on a Co-polyvinylchloride. The electrochemical study of the dye solution was carried out by repetitive cyclic voltammetry (RCV) under potentiostatic conditions in stationary and flow regime. The effect of various experimental parameters, such as potential and electrolysis time was investigated. The studies showed that for the RB5 (20 to 80 ppm) dye solutions, around 98 % of the color was removed after 60 min treatment at -3.0 V vs. SCE. It was also demonstrated that for the BY28 (15 ppm) dye solution, 6-10 cycles or low potentials (-300 mV) during 200 min electrolysis were sufficient for the decolorization of the solution. However, COD and TOC values did not decrease.

Keywords: electrochemical treatment, degradation, decolorization.
