Abstract: 

In this study, electrochemical degradation of 16 priority PAHs was examined using Ti/IrO2 anode. Iridium dioxide (IrO2) was coated by thermal decomposition of appropriate precursor solution on surface of titanium plate. Surface morphology of coated surface was observed by FESEM and XRD analysis. All electrochemical experiments were conducted using synthetic solution of PAHs in a batch cell under galvanostatic condition. GC-MS was used to quantify PAHs concentration. Electrochemical oxidation results reveal significant degradation of PAHs at Ti/IrO2 surface. Total PAHs removal was about 97 % at all studied initial pH values 3, 6 and 9 in the presence of electrolyte. Crystalline surface of Ti/IrO2 anode exhibited good electrocatalytic properties towards PAHs degradation.
