摘要:
Sulfate produced in lead acid battery processing can be recovered as sulfuric acid. A lead paste from a lead acid battery is collected and contacted with a base to produce a two-phase reaction product. The two-phase reaction product comprises a supernatant having a soluble sulfate salt and a precipitate having an insoluble lead salt. The supernatant is treated in an electrochemical flow cell to thereby produce sulfuric acid and a regenerated base.
