Separating high-valent metal ions from iron(II) chloride containing acidic solution, comprises adding aqueous solution of a phosphate compound or phosphoric acid into iron(II) chloride solution, and precipitating metal ions as phosphates

摘要

Separating metal ions having an oxidation state of = 4, from iron(II) chloride-containing acidic solution, comprises adding an aqueous solution of at least one phosphate compound or phosphoric acid into the metal ion containing iron(II) chloride solution, and precipitating the metal ions as phosphates.
