Diisododecylamine (DIDA) is shown to be an efficient agent for extracting vanadium(V) ions from weakly acidic (pH 5–6) sulfuric acid media. Its parameters are comparable with those for vanadium extraction by the well-known amine extracting agent TOA (tri-n-octylamine). The extraction of vanadium(V) ions by DIDA from the real shop leach liquors of vanadium slag with …

Vanadium is used in producing rust resistant and high speed tool steels. It is an important carbide stabilizer in making steels. About 80% of the vanadium now produced is used as ferrovanadium or as a steel additive. Vanadium foil is used as a bonding agent in cladding titanium to steel. Vanadium pentoxide is used in ceramics and as a catalyst.
