Abstract:

The textile industries in the Baghdad governorate's wastewater discharges have been found to contain Imperon Violet KB dye. The objective of this research is to examine the electrocoagulation degradation of the textile dye Imperon Violet KB in an aqueous solution with an initial concentration of 100 mg/L. Researchers looked into how EC operational factors like current density, touch time, pH, initial dye concentration, and electrolysis support affected the process. The best results occur when the current density is 1.43 mA/cm2, the time is 20 minutes, and the primary pH is 6. The removal rates for colour, turbidity, and COD were 95%, 99.5%, and 85%, respectively. The final pH changes with the original pH, while the current density remains the same, and the passage time changes. The efficiency of colour removal decreases as the initial concentration increases. Using NaCl as an electrolyte aid improved conductivity and voltage. The colour removal rate is 95.5% at a NaCl concentration of 1.6 g/L. The kinetic analysis showed that the dye breaks down according to a second-order rate equation.
