摘　　要：以电感耦合等离子体质谱法,采用水稀释样品,内标法测定酒石酸长春瑞滨中催化剂残留金属银的含量。结果表明银元素的方法检出限为0.003 ng·mL^(-1),定量限为0.009 ng·mL^(-1),线性关系良好(r>0.9995),回收率为95%~105%,RSD小于10%,并提出了此方法银元素的不确定度评定程序。The samples were dissolved by water, and silver was determined by ICP- MS method with internalstandard. The results indicated that The detection limit of silver （LOD） was 0. 003 ng ·mL-1, LOQ was 0. 009 ng ·mL-1 , the method had good linear correlation （r〉0. 9995） , and the recoveries were in the range of 95% - 105% withRSD less than 10%. The evaluation program of detection uncertainty was put forward.
