阴离子树脂-活性炭分离富集等离子体发射光谱法测定富钴锰结壳中的痕量金银铂钯

Determination of Au,Ag,Pt and Pd in Co-rich Mn-crust Samples by ICP-AES after Preconcentration Using Anion-exchange Resin and Activated Carbon

摘要: 采用717阴离子树脂活性炭联合交换分离富集技术,电感耦合等离子体发射光谱法同时测定富钴锰结壳中痕量金、银、铂、钯。方法检出限四元素分别为:Au1. 3、Ag0. 4、Pd0. 6、Pt4. 8ng/g。样品加标回收率在89. 0% ~110. 3%,相对标准偏差3. 5% ~7. 8% (n=4)。方法已用于富钴锰结壳中痕量金银铂钯的测定。

Abstract: A method for determination of Au,Ag,Pt and Pd in Co -r ich Mn-crust samples by ICP-AES was studied. A combined preconcentration metho d using anion-exchange resin and activated carbon was used. The detection limit s (ng/g) of Au, Ag, Pd, and Pt are 1.3, 0
