This International Standard gives methods for determining the silver content in photographic effluents from photographic processing wastes. Sampling, sample preservation and analytical methodology are included.

Three analytical procedures are given with two supporting sample treatment methodologies:

  1. a flame atomic absorption spectroscopy (AAS) method;

  2. two Potentiometrie iodide titration (PT) methods.

The choice of treatment is dependent on the analysis method and form of sample. Where AAS is the chosen method for analysis, cyanogen iodide-treated or preserved samples may be analysed directly. For the PT method, two digestion procedures are given: Digestion A for effluents with low salt content, and Digestion B for samples with high solids content.
