Electrochemical Destruction of Aromatic Organic Compounds for effective wastewater treatment

Abstract

The research is devoted to the study of the destruction of aromatic organic compound – 1,3-dihydroxybenzene by electrochemical oxidation process. Impact assessment was carried out during the process of such parameters as the concentration 1,3-dihydroxybenzene, nature of medium (pH), electrolysis time, organic matter conversion coefficient, electrochemical cell configuration. Electrochemical destruction process was actualized in coaxial membraneless electrochemical reactor with coaxial electrode arrangement achieving the effective mass-transfer. The results of current density diversification and pH approved the optimal terms to be the current density 4 κA/M2, pH = 11,0. Assessment of conversion coefficient of 1,3-dihydroxybenzene was estimated by spectrophotometric method. Conversion coefficient of 1,3-dihydroxybenzene was 95,78% during 3 hours of electrolysis.
