| 520 | _ | _ | |a As all existed in the form of anion, the separation of vanadium (V) and chromium (Ⅵ) in weak acid solution was a difficult issue. The study developed an efficient way to achieve the separation of V(V) and Cr(Ⅵ) based on the steric hindrance effect of amide extractants. The effects of different parameters on extraction were studied to explore the optimum conditions. The recoveries of vanadium and chromium were above 97.0% and 99.8%, respectively. The extraction of vanadium with amide was an exothermic reaction. The purity of V2O5 obtained was 99.97%. The V(V) complex of amide was confirmed to be R2H6V10O28. The extraction mechanism was studied with ESI-MS and FT-IR in depth. The extraction of V(V) with amide followed ion association with hydrogen bonding. A promising way was provided to separate vanadium (V) and chromium (Ⅵ) in leaching solution with amide under weak acid condition. |
