This standard BS ISO 7766:2003 Processing photographic wastes. Analysis of cyanides. Determination of hexacyanoferrate(II) and hexacyanoferrate(III) by spectrometry is classified in these ICS categories:
- 37.040.30 Photographic chemicals
- 13.030.30 Special wastes
This International Standard establishes a test method for the determination of hexacyanoferrate(II) (ferrocyanide) and hexacyanoferrate(III) (ferricyanide), referred to hereafter as Fe(CN)6, in photographic processing effluents1). Results are reported as hexacyanoferrate, Fe(CN)6.
