摘要
通过硝酸铅沉淀分离基体铅、有效富集高纯铅中镁、铝、钙、铁、镍、钴、锰、铜、锌、砷、硒、镉、铟、锡、锑、碲、铊、铋等18种杂质,通过电感耦合等离子体质谱测定高纯铅中18种杂质,测定下限在0.04～0.32μg/mL,加标回收率为80%～108%,测定精密度(RSD)为2.5%～14%。
The impurities in high-purity lead were determined by ICP-MS after preconcentrated through precipitation of lead nitrate. A method for the determination of 18 impurities in high-purity lead was developed. Determination limits of all elements are between 0. 04μg/g and 0. 32μg/g. High-purity lead was determined. RSDs are 2. 5% - 14%. Recoveries obtained are 80% - 108%
