Abstract
It is feasible and advisable to regenerate the solutions formed during desulfation of lead materials by aqueous sodium hydroxide solutions f or reuse of the caustic in a closed cycle. It has been proved experime ntally that regeneration of such solutions with powdered calcium oxide is quite ineffective. Application of barium hydroxide gives considera bly better results.
