Photography. Processing wastes. Determination of silver content Ingestion-build-132972 This International Standard sets out1 Scope 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: a) a flame atomic absorption spectroscopy (AAS) method; b) two Potentiometrie iodide titration (PT) methods. The choice of treatment is dependent
