Removal of high concentration phenol from aqueous solutions by electrochemical technique


In this study, the ability of the electrochemical process to remove aqueoushigh concentration phenol using an electrochemical cell with aluminumanode and cathode was examined. The removal rate of phenol wasmonitored using different parameters phenol concentration, pH,electrolysis time, current density, and electrode distance. Obtained resultsindicated that the low removal rates of phenol were observed at both lowand high pH. However, the removal rate of phenol increased with anincrease in the current density, each electrochemical process conditionsneed a certain electrodes distance. removal rate of phenol decreased withthe increase in the initial phenol concentration. The maximum removal rateof phenol obtained from this study was 82%.
