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%.
