Notes:
An X-ray fluorescence method has been developed to determine the metal concentration in the aqueous and organic phases from solvent extraction processes. The method has been specifically applied to the determination of copper, but can be extended to include other elements which form soluble organic complexes. Accuracy and precision are comparable with that obtainable by the electrogravimetric technique for the analysis of copper in aqueous solution, but are superior to the atomic absorption analysis of copper in organic solution. Rapid analysis is achieved by presenting a diluted sample directly to the spectrometer. Inter-element absorption enhancement effects are corrected by the selection of a suitable internal standard which is added to the diluent.
