Authors : Benmani F. . Cheknane B. . Zermane F. . Aoudj S. .
Abstract
In this work, the removal of two cationic dyes {greenmethyl and basicyellow 28} by electro coagulation using aluminium as anode and stainless steel as cathode was studied. First, the effect of the most important parameters {current intensity, initial pH of and initial concentration} on decolorization in single system was investigated. The results showed that the pollutants are totally removed (with efficiently of 100 %) and the adsorption kinetics was directly related of the pollutant nature and the operating conditions such as (Initial pH, concentration and contact time). Secondly, the removal of the dyes in a binary system was studied. Results showed that adding BY28 affects positively the removal of GM by increasing the removal of the BY 28, which can be explained by synergic effect of decolorization.
