Abstract

The effects on the extraction of Vanadium(V) by N-(2-hydroxy-5-nonylbenzyl)-β,β-dihydroxyethylamine of different factors, including pH of the medium, concentration of extracting agent, temperature and solvent type, were studied. This allows the optimal extraction conditions to be determined. It is shown that extraction of Vanadium(V) takes place with high distribution coefficients and that, in the organic phase, a complex is formed which contains a decavanadate anion and four molecules of the extracting agent. The extracted Vanadium(V) amine complex is stable for more than one month.
