SELECTIVE EXTRACTION-SPECTROPHOTOMETRIC METHOD FOR DETERMINING COBALT WITH 1-(2-PYRIDILAZO)-2-NAPHTHOLE (PAN)

Abstract

The conditions for selective extraction of cobalt (II) with inert organic solvents from a strongly acidic medium in the presence of dimethylformamide (DMF) and its complexation with the PAN reagent directly in the organic phase were studied. As a result, a selective extraction-spectrophotometric method for the determination of cobalt with PAN was developed. The developed method is recommended for the determination of cobalt from ores, concentrates, steels and other materials with complex chemical compositions without prior separation of associated elements.

Keywords

selective, ecoanalytical, extraction-photometric, extraction-spectrophotometric, spectra of extracts, equilibrium shift method, solvation number, hydrate-solvation mechanism
