摘要
烟丝样品经烘干磨碎、用硝酸消化后直接上机测定,方法简便、快速、灵敏测定Pb、Cd的绝对灵敏度分别为2.67×10^(-11)g和2.72×10^(12)g,回收率分别为102%和103%.
The sample was dissolved with HNO_3 after direct determination.The method was simple convenient rapid and sensitive.The absolute sensitivity of Cadmium was 2.72×10^(-12)g and Lead was 2.67×10^(-11)g.The recovery of cadmium was 103% and Lead was 102%.
