Abstract
Photoelectrocoagulation treatment of aqueous solution containing, rhodamine B has been studied. Three different supporting electrolytes such as NaCl, NaNO3 and Na2SO4 were used for electrolysis. Only NaCl was found to be effective for the removal of colour from rhodamine B dye. Effects of the process variables such as pH, applied current density, electrode material, supporting electrolytes types, different concentration of electrolyte and treatment time were explored in order to find the best conditions for the degradation of rhodamine B. The complete degradation was obtained in 35 min of operating time for Fe electrode at optimum conditions such as initial pH 7.0, supporting electrolyte of 0.05 M NaCl and applied current density of 10 mA/cm2 and treatment time of 35 min. Sludge characterization was analyzed by FT-IR spectra and the morphology of sludge was characterized by SEM were discussed. The SEM image confirmed the characteristics of phases, which are amorphous or poorly crystalline in nature.
