摘    要:利用电感耦合等离子质谱技术建立了直接测定高纯金属铜中11个杂质元素的分析方法,并研究了分析线的选择、基体的干扰、检出限的优化以及回收率的测定。方法的检出限为0.003~0.040μg/mL,回收率为94.8%~107.2%,RSD小于4.7%。结果表明,该法准确、快速、简便,应用于金属铜中杂质元素的测定,结果令人满意。

关 键 词:电感耦合等离子发射光谱法(ICP-AES)  高纯金属铜  杂质元素

Abstract:A new analytical method used for direct determination of eleven impurity elements in the high-puritymetallic copper by Inductively Coupled Plasma/Atomic Emission Spectroscopy(ICP/AES) is established.The problems of selection of the analytic line,the disturbance of substrate,the optimization of detection limit and determination of recovery are researched.The detection limit of this method is 0.003~0.040μg/mL,the recovery is 94.8%~107.2%.Relative standard deviation(RSD) is less 4.7%.The test results indicated that this method possesses advantages of accuracy,quick,convenient and others.The analytical results are satisfactory when applied in determination of impurity elements in metallic copper.
Keywords:ICP/AES  High-purity metallic copper  Impurity elements
