| 摘 要： | 用P204+TBP+磺化煤油体系从废钒催化剂还原酸浸液中萃取回收钒,考察萃取相比(O/A)、P204浓度及待萃液初始pH对萃取钒的影响。结果表明,P204萃取钒最优条件为:萃取剂组成20%P204+10%TBP+70%磺化煤油、相比O/A=2、料液初始pH=2.2、萃取5 min。在此优化条件下,VO2+萃取率可达98.73%。用1.5mol/L硫酸反萃6min,VO2+反萃率达93.35%,且制得V2O5产品达GB 3283-1987冶金99级V2O5的标准。

| Abstract: | Vanadium was extracted from acid reduction leaching solution of waste vanadium catalyst in P204 TBP sulfonated kerosene system. The effects of phase ratio (O/A), P204 concentration and initial pH value of extraction solution on vanadium extraction were investigated. The results show that vanadium extraction rate is 98.73% under the optimum conditions including extraction system of 20%P204 10%TBP 70% sulfonated kerosene, O/A=2, initial pH value of feeding solution of 2.2, and extracting duration of 5 min. Vanadium stripping rate is 89.91% with 1.5 mol/L sulfuric acid as stripping agent for 6 min. The final product of V2O5 could meet standard of GB 3283-1987 Metallurgical Grade 99 V2O5. |
