摘要: Abstract The dye malachite green (MG) has found extensive use all over the world in fish farming industry as a fungicide. It been suspected to be genotoxic and carcinogenic it now become highly controversial compound due risks poses consumers of treated fish. In this context, electrochemical oxidation studied on one-compartment batch reactor employing boron-doped diamond (BDD) anode stainless steel cathode. effects several experimental parameters, such current density, pH initial supporting electrolyte were investigated. optimal conditions determined intensity 32 mA cm− 2, strongly acidic (pH = 3), Na2SO4 good electrolyte. Under these conditions, degradation efficiency 98% was obtained after 60 min electrolysis 91% chemical oxygen demand (COD) removal 180 min electrolysis.
