This article reports the removal of chromium by electrocoagulation (EC) from metal complex dye (MCD) industrial effluent in a batch reactor using iron electrodes. The paper evaluates the application of EC process in assessing the impact of process parameters such as current density (CD), electrode distance (ED), pH, and supporting electrolyte (NaCl) concentration (Cs) for efficient removal of chromium from MCD effluent. The EC process showed, removal percentage 99.64 %, at the initial pH= 5.83, CD = 89.45 A/m2, ED= 0.7 cm, and operating time of 50 minutes, are the optimal operating parameters for the treatment of MCD effluent. It was also noticed that the removal of chromium is appreciably enhanced for acidic pH values. It was observed that the removal of chromium follows the 1st order reaction by kinetic analysis of EC method. As CD raised from 17.89 to 89.45 A/m2. The rate constant (k) was enhanced from 0.013 to 0.109 min-1, as a result of the presence of more quantity of iron flocs throughout EC. Analysis of sludge was carried out using FESEM- EDX, which confirmed the presence of chromium, and iron hydroxide in sludge. The present work confirms that EC is an efficient process for chromium removal from MCD effluent with a calculated operating cost of 0.207 US$/m3 and energy consumption of 2.499 kWh/m3.
