中文摘要: 采用稀盐酸浸泡法脱除氧化钪产品中的钙,考察稀盐酸浓度、浸泡时间、液固比、浸泡温度、CN试剂加入量对氧化钪产品中钙脱除率和钪损失率的影响。结果表明,最佳条件为:稀盐酸浓度1.2 mol/L、常温浸泡60 min、液固比2︰1、CN试剂用量为氧化钪量的4%。经过二次稀盐酸浸泡处理的氧化钪产品可以达到GB/T 13219-2010中161040级产品牌号的标准。
Abstract:Calcium in Sc2O3 product was removed by immersion with dilute hydrochloric acid. Effects of dilute hydrochloric acid concentration, immersion time, L/S, immersion temperature, and dosage of CN reagent on calcium removal rate and scandium loss ratio were investigated. The results show that the optimum conditions include dilute hydrochloric acid concentration of 1.2 mol/L, immersion at room temperature for 60 min, L/S=2︰1, and dosage of CN reagent of 4% mass fraction of Sc2O3. Sc2O3 product can meet the requirement of Grade 161040 of GB/T 13219-2010 standard after twice immersion of dilute hydrochloric acid.
