Erbium oxide (Er₂O₃) with a relative purity of 99.99% was separated and purified at room temperature (25 ℃) by ion exchange, and effects of acidity and flow rate of eluent on the separation and purification were investigated. Two ion exchange columns were connected in series, and hydrochloric acid with acidity of 1.5 mol/L was taken as the eluent at a flow rate of 5 L/h in column 1 and 10 L/h in column 2. After separation and purification under the above optimal conditions, erbium oxide had a relative purity greater than 99.999 9%, with the total content of rare earth impurities less than 1 μg/g. This study provides an effective process, featuring low energy consumption, short flow and low costs, for separation and purification of heavy rare earths.

在室温（25 ℃）下，以相对纯度为99.99%的氧化铒（Er₂O₃）为原料，采用离子交换法进行分离提纯，探究淋洗液酸度和淋洗流速对分离提纯效果的影响。结果表明，氧化铒分离提纯的适宜工艺条件为：将2根离子交换柱串联，淋洗剂为盐酸，淋洗液酸度为1.5 mol/L，淋洗流速为1号柱5 L/h、2号柱10 L/h，该条件下氧化铒产品中稀土杂质含量低于1 μg/g，氧化铒相对纯度大于99.999 9%。本研究为重稀土分离提纯提供了一种能耗低、流程短、成本低的有效工艺。
