ABSTRACT:
A method for determining the alkali metal content of a liquid such as protein-containing liquids wherein a liquid containing alkali metal cation is contacted with a monocyclic crown ether capable of forming a complex with the alkali metal cation in a substantially inert solvent and an anionic dye, is disclosed. The alkali metal forms a complex with the ether and the dye in the solvent, the presence of which is a measure of the alkali metal content of the liquid.
