Abstract
A method for determining both the inorganic and the metallo-organic salt content in an organic solvent. A salt-free polar solvent is added to and is mixed with a sample of an organic solvent to be analyzed, producing a two-phase intermediate solution. The intermediate soluton is mixed with and is dissolved in another salt-free solvent in which the polar solvent and the organic solvent are mutually soluble, producing a one-phase final solution. The total salt content (inorganic plus metallo-organic) of the final solution is determined by conventional techniques such as, flame photometry or atomic adsorption spectrometry.
