METHOD OF VANADIUM EXTRACTION |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: to extract vanadium extraction from water solution with di-2-ethylhexylphosphorous acid in organic thinner is carried out. Preliminarily sulphuric acid is added to water solution until its concentration in solution is not less than 7.0 mol/l. Extraction is carried out with volume ratio of water and organic phase equal 2:1. ^ EFFECT: simplification of method of vanadium extraction from water solutions with increase of its extraction degree. ^ 5 ex |
