A Study of the Low Current Density Electrolysis of Ammonium Thiosulfate Fixers

Determinations of the current tolerences of sodium thiosulfate and ammonium thiosulfate fixers are made and compared. The rate of fixation of ammonium thiosulfate fixer before and after electrolysis is studied. The current efficiency of low current density electrolysis in ammonium thiosulfate is found. Causes and forms of sulfiding are discussed and related to the work of the experimenter
