| 摘 要： | 研究了P507-N235混合萃取剂分离石煤酸浸液中钒与铁的工艺,考察了N235/P507浓度、萃原液pH、萃取时间、相比(A/O)对钒、铁萃取率及钒铁分离效果的影响。结果表明,采用0.4 mol/L P507,0.8mol/L N235为萃取剂,磺化煤油为稀释剂,pH=1.7,萃取时间5min,A/O=5/1,经4级萃取,钒萃取率可达98.36%,而铁萃取率仅为5.78%。相对现有的P204、P507单一体系,P507-N235体系具有更好的萃取能力及钒铁分离性能。

| Abstract: | The process to separate vanadium and iron in stone coal acidic leaching solution with P507-N235 mixed extractant was studied. Effects of concentration of N235/P507, initial pH value, extraction time, and phase ratio (A/O) on extraction efficiency and separation performance of vanadium and iron were investigated. The results show that after four-stage extraction, extraction rate of vanadium and iron is 98.36% and 5.78% respectively under the optimum conditions including 0.4 mol/L P507, 0.8 mol/L N235, initial pH value of 1.7, extraction time of 5 min, and A/O=5/1. Compared with P204 system and P507 system, P507-N235 system has higher vanadium extraction efficiency and better separation performance of vanadium and iron. |
