Abstract
The removal of reactive dye from effluents by electrocoagulation has become an attractive
method in recent years. This paper deals with the removal of the reactive dye Fast Sulphon Black F
from an aqueous medium by the electrochemical method using platinised titanium, mild steel,
aluminium, Copper and stainless steel electrodes. The effects of electrolyte concentration, initial pH,
current density, electrode area, interelectrode distance, dye concentration, and treatment time on the
decolorization efficiency have been investigated. The optical density of the dye solution was measured
before and after electrolysis, and hence the decolourisation efficiency (DE) was calculated. UV
spectroscopy has been used to investigate the nature of dye before and after decolourisation. The
decolourisation efficiency is in the decreasing order Pt/Ti>Cu>SS>Mild Steel>Al.
