Understanding the effect of electro-oxidation process variables on reactive navy blue rx dye decolorization

Abstract

The study investigated the study of electro-oxidation treatment on Reactive Navy Blue RX dye simulated wastewater using graphite and stainless steel electrode material as anode-cathode assembly. The effect of initial pH, electrolyte dose, applied current, dye concentration, and time, has been investigated. Preliminary test to understand influence of initial pH and NaCl dose on EO process has also been investigated and further work was carried at optimized initial pH 5 and NaCl dose 500 mg/L. From the experiments it was observed that with increase in current density the color removal also increases while with increase in initial dye concentration, removal efficiencies decreases.
