摘要:
The invention concerns a method for decreasing the oxygen content of the atmosphere above photographic processing baths. The method comprises using a solid electrolyte which is a compound of bismuth, vanadium or another transition metal. The oxidation in air is thus minimized and the life of the bath is extended.
