Abstract

Removal of Ag ions from photographic bleach-fix solns. comprises: (a) adding a seleno- or meracapto-tri-or tetrazole, bis-tri or -tetra-azole diselined or disulphide or 5,5'-bis-(1,2,4-triazolo-3 -selenol or thiol), in which the tri- and tetra-azoles can be substd.; and (b) removing the Ag pptd. as complex seleno- or mercapto-cpd. The pptd. can be filtered easily, making special tretment (e.g. centrifuging) unnecessary.
