ELECTROCHEMICAL TREATMENT OF AIRPORT RUNOFF WATER CONTAINING ETHYLENE GLYCOL
Airports are one of the sources of environmental pollution with runoff water containing emerging contaminants. The process of electrochemical purification of model runoff water containing ethylene glycol and formed during the treatment of aircraft with anti-icing agents was studied. As an anode there was used PbO2 electrode. The structure and morphology of PbO2 electrode samples obtained by electrochemical deposition on the titanium plate surface was studied using scanning electron microscopy. It revealed that the use of PbO2 as an anode makes it possible to bring the COD value of the solution to the required standards. After electrolysis, the COD values for all studied ethylene glycol concentrations from 10 to 100 mg/l were in the range of 0.34-4.6 mgO2/l. The effect of current density, concentration of ethylene glycol and sodium chloride on the efficiency of electrochemical oxidation of ethylene glycol was analyzed.
