摘要
研究了用ＩＣＰ－ＡＥＳ法测定Ａｕ－Ｂｅ合金中Ｂｅ及萃取Ａｕ后测定微量Ｐｔ、Ｐｄ、Ｒｈ、Ｉｒ、Ａｇ等２５个杂质元素的方法。元素间的干扰用等效浓度法校正。杂质元素标准加入回收率为９６～１０７％，相对标准偏差为１．７％～１２％。取２．５ｇ试样时相对分析下限为１×１０－４～５×１０－４％。测定合金成分Ｂｅ时相对误差不大于２％。
An ICP AES method was established for the determination of Be and impurity elements in Au Be Alloy ,such as platinum,palladium,rhodium,iridium,silver etc.The interference was corrected by using the equivalant concentration technique.The detection limit in 2 5 g sample varied from 5×10 -5 to 2×10 -4 %.The ralative error for Be was less than 2%.
