Electrochemical methods for decontamination of industrial waste of the gas nitrogen oxide (II)

The paper shows the electrochemical oxidation of nitric oxide (II) in a solution of potassium hydroxide using lump electrodes. The influence of the current density of the lump electrode, the electrolyte concentration, the thickness of the lump electrode and the gas volume on the oxidation current and the degree of oxidation of nitric oxide (II) is considered. The study was conducted in galvanostatic condition in a thermostated electrolysis with a volume of 100 ml. Nitric oxide gas was supplied at a certain rate to the bottom of the anode space of the electrolyzer. In the main experiments, the volume of gas sent to the electrolyzer is 300 ml. The gate was regulated by a three-way valve, and electrolysis was carried out for 0.5 hours.
