摘要：

The electrochemical study shows that phosphate ions oxidation on BDD (Boron Doped Diamond) occurs before oxygen evolution in aqueous mild. The reaction rate is enhanced in a basic solution. With voltametric studies it is shown that oxidation current is linearly dependent on phosphate ions concentration and potential scan rate. The electro-chemical mechanism is very complex and involves several steps with adsorbed species and radicals. The electrolysis at fixed potential leads to peroxodiphosphate species formation in solution. The complexity of electrochemical mechanism is confirmed by EIS study. EIS measurements demonstrate also that BDD electrode-electrolyte behavior is compatible to p-type semiconductor with 1.49 Vas plate band potential.
