Determination of 14 Rare Earth Impurities in High Purity Europium Oxide by Axis-view ICP-AES with Chromatographic Separation

Publish Date: 28 June 1994

摘要: 对Ｐ５０７萃淋树脂分离稀土元素的条件进行了实验，拟定了以Ｐ５０７萃淋树脂为固定相，ＨＣｌ为流动相分离４Ｎ级荧光材料Ｅｕ＿２Ｏ＿３中１４种稀土杂质元素的流程，使被测杂质与基体Ｅｕ＿２Ｏ＿３达到了较好的分离；再用阳离子交换树脂分离被测液中非稀土杂质元素。选择了端视ＩＣＰ－ＡＥＳ测量稀土杂质元素的最佳条件。称样量５０ｍｇ时各杂质组分的测定下限（ｕｇ／ｇ）为：ＣｅＯ＿２、Ｐｒ＿６Ｏ＿（１１）、Ｎｄ＿２Ｏ＿３、Ｓｍ＿２Ｏ＿３、Ｔｂ＿４Ｏ＿７、Ｈｏ＿２Ｏ＿３、Ｅｒ＿２Ｏ＿３，Ｔｍ＿２Ｏ＿３、Ｌｕ＿２Ｏ＿３０．４，Ｌａ
