Solvent Extraction of Vanadium from Nigerian Bitumen Using Tri-Butylphosphate
I.I. Oguntimehin and K.O. Ipinmoroti

Abstract:
The equilibrium extraction of vanadium (V) from bitumen in Nigeria was carried out with Tributyl Phosphate (TBP) in nitric acid medium in pH range of 1.00-3.50. The extraction concentration was in the range 15-60% TBP in n-hexane and in temperature range of 27 to 50°C. The initial aqueous vanadium (V) concentration varied between 1x10-4 and 1x10-3 M. The extraction of the vanadium was most favorable at pH 2.8, 41.5°C (≈ 315K) and 7.8x10-4 M concentration of aqueous vanadium. However, increased concentration of the extractant beyond 40% did not favour the extraction of vanadium. The bitumen samples from Agbabu and Igbokoda analyzed contained 44.64±1.8x10-1 and 31.58±2.3x10-1 mg kg-1 of vanadium, respectively.
