Removal of Gentian Violet Dye With and Without Commer- cial Activated Carbon by Electro Coagulation Technique - A Comparison

摘要

Present study deals with the comparison of electro coagulation treatment of colour and dye with and without commercial activated carbon (CAC) and determination of optimum conditions for the removal of gentian violet (GV) from water. This study has its own application in the removal of gentian violet (GV) from industrial effluents. Experimental results will be highly useful in designing the effluent treatment plant, for the removal of dyes. Percentage of removal of gentian violet (GV) is found to increase with decrease in initial concentration and initial pH. Percentage removal of GV is found to increase with increase in electrolyte concentration, treatment time and voltage. Percentage removal of GV in presence of CAC is more than without CAC in this study. It is concluded from the results of present study, that the electro coagulation in presence of CAC could be used for the removal of gentian violet (GV) from wastewater. Electro coagulation in presence of CAC is useful for the treatment of textile effluent for the removal of colour and dye.
