An environmentally friendly process for efficient separation and recovery of V(V) from aqueous solution containing Cr(VI) was proposed using the new task-specific ionic liquid of [C12H25NH3][Cyanex 272]. The separation factor of V(V) from Cr(VI) was about 1.08 × 103 with the optimum extraction conditions, and the extraction percentage of V(V) was about 99.5 %. The loaded organic phase was stripped using the NH3·H2O, and the recovered NH4VO3 was obtained with the processes of stripping, filtration, washing, and desiccation. The qualitative analysis of the recovered NH4VO3 was made using the X-ray diffraction, and its peaks were good consistent with the standard sample. Morphology of the recovered NH4VO3 was also studied using the scanning electron microscope. The extraction mechanism of V(V) using the [C12H25NH3][Cyanex 272] was investigated using the slope method and infrared spectrum analysis. This new environmentally friendly process can be used for the separation and recovery of V(V) from real leaching solution with the aim of industrial application. |
