    Environmentally Safe Technology for Preparing Metal Oxide Anode
    (Видавництво Львівської політехніки, 2022-03-01) Mykhaylenko, Volodymyr; Gil, Zinaida; Lukianov, Yevgeniy; Lukianova, Olha; Khinevich, Oleksandr; Antonov, Oleksiy; National Academy of Sciences of Ukraine
    The article is devoted to the development of lowwaste environmentally safe technology for the production of combined metal oxide anodes. Low waste is realized due to recycling of nitrogen oxides and heavy metal compounds. It is established that the depth of purification of air from nitrogen oxides with water with neutralization of nitric acid with manganese carbonate exceeds 95 %. It was determined that the residual concentrations of heavy metals of lead and copper in treated wastewater do not exceed, respectively, 0.002 and 0.06 mg/m3. The resulting manganese nitrate and lead and copper hydroxides are returned to anode production.
