| 摘 要： | 用ICP-AES基体匹配法测定了高导电铜中Ni，Be，Mg，Co和Si等微量元素含量，同时对所测元素相对不确定度进行了考察.发现以质量比计，元素Ni，Mg，Be，Co，Si的含量分别为2.13，0.088，0，0，0.22 mg/kg；相对不确定度主要由测量精密度和回收率2个因素决定.

| Abstract: | The ICP-AES matrix matching method has been applied to determine the trace elements Ni,Be,Co,and Si in high conductivity copper,and the uncertainty of those elements has been analyzed.The results showed that the mass ratios of those elements were:Ni 2.13 mg/kg,Mg 0.088 mg/kg,Be 0 mg/kg,Co 0 mg/kg,Si 0.22 mg/kg and the main factors which determine the uncertainty were the measurement repeatability and recovery rate. |
