PRODUCTION DE MONOXYDE DE PLOMB A PARTIR DE SULFATE DE PLOMB AU MOYEN D'ACIDE ACETIQUE |
摘要 |
An efficient and inexpensive method for producing lead monoxide from lead sulfate bearing materials such as recycled battery mud is provided comprising: (a) reacting said material with an ammonium carbonate solution to convert lead sulfate to lead carbonate; (b) decomposing the lead carbonate to form impure lead monoxide; (c) reacting the impure lead monoxide with acetic acid to form a lead acetate solution; (d) contacting the lead acetate solution with carbon dioxide to produce insoluble lead carbonate; and (e) decomposing the lead carbonate to form lead monoxide. <IMAGE> |
