DISTRIBUTION OF METAL CATIONS IN THE AQUEOUS STRATIFIED SYSTEM OF ANTIPYRINE, SODIUM SULFATE

Abstract

The possibilities of a new exfoliating extraction system without organic solvents with the participation of antipyrine, sodium sulfate and water are studied. The optimal conditions for delamination of the aqueous system are determined depending on the concentration of the components. It is shown that the organic phase is used to extract complexes of the introduction of macroquantities of gallium (III), indium (III), thallium (III), and scandium (III). The physicochemical and chemical methods determine the ratios of the components in the complexes. The antipyrine-sodium sulphate-water separation system is proposed for the isolation and determination of microquantities of Fe (III), In, Sc, Mo, and Th using an inductively coupled plasma emis- sion spectrometer iCAP 6500.
