Evaluation of Electro Coagulation Process Performances for Decolorization of Alizarin Saphirol Containing Solution

Abstract:

Electro coagulation represents a good alternative to the conventional treatment techniques for dye containing wastewaters. In this paper, electrochemical coagulation efficiency (expressed in terms of colour removal degree) with aluminum and iron sacrificial anodes has been tested on an Alizarin Saphirol containing solution, an acid dye that belongs to antraquinone class. The influence of electrolysis time, operating current density, pH value and anodic material type on process performances was investigated. It has been concluded from experimental results analysis that the solution can be effectively treated using electro coagulation. The maximum removal efficiency, 99% was recorded at 200 A/m2, pH=6, after 12 min. Keywords: electro coagulation, sacrificial anode, Alizarin Saphirol, antraquinonic dye, wastewater treatment
