Abstract:
The Taguchi method was applied as an experimental design to determine optimum conditions for color removal from azo dyes solutions containing remazol yellow G by electrocoagulation (EC)using iron and steel electrodes as anode and cathode, respectively. An orthogonal array (OAexperimental design that allows to investigate the simultaneous variations of four para (initial remazol yellow G concentration, initial pH of the solution, time of electrolysis and currentdensity) having three levels was employed to evaluate the effects of experimental parameters. Performance measure analysis was followed by perform determine the optimum levels and relative magnitude of the effect of parameters. The desiredcharacteristic for response has been maximum decolorization, therefore, Taguchi’s ‘the larger the better’ performance formula yellow G concentration, 100 current density, 1 mAcm-2.
