Sodium and Potassium by Atomic Absorption Spectrophotometry

VIEW METHOD

Objective
A representative sample is dry-ashed. Residue is dissolved in acid and diluted to a known volume. This solution, or a dilution thereof, is analyzed for sodium and potassium content by atomic absorption spectrophotometry. Cesium chloride is added to all solutions (standards, samples, and blank) as an ionization suppressant. This method is applicable to flour and cereal products.
