    摘要: The useful life and stability of fixer used in the processing of film through developer, fixer and wash stages is significantly improved by withdrawing used fixer, electrolytically removing silver therefrom, stabilizing the withdrawn fixer by adjusting its pH to a substantially constant value and recirculating thus-treated used fixer for further film processing.
