Experimental study on precipitation of ammonium metavanadate in NaVO3-H2O system by ammonium bicarbonate and ammonium carbonate

  • 摘要: 针对钒渣钠法提钒得到的NaVO3-H2O溶液体系,利用碳酸氢铵/碳酸铵作为铵盐,考察了沉淀pH值、沉淀温度、结晶时间、加铵系数对偏钒酸铵结晶效果的影响。结果表明:在一定范围内提高溶液的pH值(9.1~9.5),可以改善偏钒酸铵的结晶率;在温度15~27 ℃、结晶时间>3 h、加铵系数不小于2.9条件下,可实现偏钒酸铵结晶率>85%,经煅烧获得的五氧化二钒纯度>99.3%,满足YB/T 5304—2017质量标准要求。
