| Abstract: |
| Effects of carrier concentration, diluent type, stripper type and concentration, and pH value of solution on vanadium extraction from simulated quartz acid leachate with N235 as extraction were studied. Separation of Fe, P and Al from vanadium and leaching solution was investigated. The results show that extraction rate of vanadium is 87.73% under the optimum conditions including pore size of the support membrane of 0.22 μm, stripping agent concentration of Na2CO3 of 0.6 mol/L, kerosene as diluents, extractant concentration of 10%, pH value of feed solution of 1.8, and extraction time of 13 h. Separation coefficients of impurity ions iron, aluminum and phosphorus relative to vanadium are 191.8, 350.3 and 163.0 respectively, which indicates that supporting liquid membrane technology has better effect on separation and enrichment of vanadium. |
