  • Electrolyte for electrochemical decontamination and preparation method and application thereof
    Patent number: 11342092
    Abstract: An electrolyte for electrochemical decontamination and a preparation method and application thereof. The electrolyte is an aqueous solution including the following solutes: phosphoric acid, oxalic acid, citric acid, tartaric acid, hydrogen peroxide and glacial acetic acid. The electrolyte has a good decontamination effect and allows for fast decontamination and is obtained by reasonably combining different types of solutes and controlling the levels of the solutes and resulting secondary waste solution and residues are easy to treat. The electrolyte is suitable for overall or local electrochemical decontamination of radioactively contaminated stainless steel scrap.
