Abstract
The electrochemical oxidation of nitrofurazone with SnO2, doped by platinum group metals, and pure PbO2 has been investigated. Тhe oxidation rate of nitrofurazone with PbO2-anode is 5.3 times higher compared to doped SnO2 anodes. It was found that the presence of 1; 2 and 3 g l−1 NaCl in electrolyte affects the efficiency of the electrooxidation process in the case of doped SnO2 anodes, the oxidation rate of nitrofurazone increases by 2.3; 3.7; 5.8 times, respectively. Using of doped SnO2 in chloride-containing media allows one to achieve the same rate of destruction of nitrofurazone as when using lead dioxide. Moreover, SnO2 doped electrodes are characterized by the production of a large number of hypochlorous acid and have a higher service life compared to PbO2 in such harsh conditions.
