Description / Abstract: Three analytical procedures are given with two supporting sample treatment methodologies: a flame atomic absorption spectroscopy (AAS) method and two potentiometric iodide titration (PT) methods. The choice of treatment is dependent on the analysis method and form of sample. The AAS method allows cyanogen iodide-treated or preserved samples to be analyzed directly, the PT method requires one of two digestion procedures given.
