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:Au 1.3、Ag 0.4、Pd 0.6、Pt 4.8 ng/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.
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, 0.4, 0.6 and 4.8,respectively. The recov eries with standard addition for Au,Ag,Pt and Pd range from 89.0%~110.3% with precision of 3.5%~7.8% RSD(n=4). The method shows advantages of high accura cy, simple and convenient operation. The method has been applied to the determi nation of Au,Ag,Pt and Pd in Co-rich Mn-crust samples with satisfactory resu lts.
