发明名称 ELECTROCHEMICAL RECOVERY OF SILVER AND REGENERATION OF USED PHOTOGRAPHIC FIXING SOLUTIONS
摘要 An improved method for recovering silver and regenerating used photographic fixing solutions electrochemically is disclosed whereby silver is electroplated from used fixing solutions using high-current densities, e.g. 300 a./ft.2, without decomposing the fixing solution. The fixing solution is then capable of being reused in the photographic process.
