中文摘要: 利用石煤钒矿浸出液中的钒和铁直接制备钒酸铁,考察了氧化剂种类及过量系数、时间、pH、温度对沉淀钒酸铁的影响。确定了石煤钒浸出液沉淀钒酸铁的最佳工艺参数:氧化剂氯酸钠的过量系数1.4、反应时间5 h、pH=2.5、反应温度90~95 ℃,V2O5沉淀率达到93.73%。
Abstract:Ferric vanadate was prepared from coal vanadium ore leaching solution. The effects of type and dosage of oxidant, reaction time, pH value, and temperature on precipitation were investigated. V2O5 precipitation rate is 93.73% under the optimum conditions including dosage of sodium chlorate of 1.4 times of theoretical value, reaction time of 5 h, pH value of 2.5, and reaction temperature of 90~95 ℃.
