RESEARCH INFLUENCE OF TEMPERATURE AND SCAN SPEED TO CYCLIC VOLTAMMETRY CURVES ON OXIDATION OF PHENOL USING Ti/SnO2-Sb2O3/PbO2 ELECTRODE

Abstract

Phenol and its derivatives have been widely used in industries such as formaldehyde resins, pharmaceuticals, pesticides, textiles, dyes and refineries. When discharged into the environment, due to the toxicity of phenols and organic compounds, they will have an adverse effect on microbial growth, so it is necessary to treat them in wastewater. One of the methods of removing phenol is the use of electrodes such as inert anodes (DSA). However, the ability to degrade phenol by electrochemical oxidation during electrolysis depends on many factors, including temperature and potential scanning rate. In this paper, the author studied the effect of temperature and potential scanning speed on Cyclic Voltammetry (CV) in the oxidation of phenol. Research results show that phenol can be oxidized electrochemically on Ti/Sb2O3-SnO2/PbO2 anode electrode at temperature of 30oC, electrolytic environment pH = 8 and scanning speed of 50mV/s.
