摘要
研究了介质浓度 ,基体排除 ,共存元素等对火焰原子吸收光谱法测定锡锭中镉、铋、铁的影响。方法的相对标准偏差小于 6 % ,加标回收率在 95 %～ 10 6 %之间 ,灵敏度镉为 0 .0 0 97μg· m L- 1 · 1% - 1 ,铋为 0 .19μg· m L- 1 · 1% - 1 ,铁为 0 .0 5 0μg· m L- 1 · 1% - 1 ,方法简便 ,准确可靠。
The effects of agent concentration,matrix speration and simultaneous element on the determination of cadmium,bismuth and iron in tin slab were studied.The relative standard deviation was smaller than 6%,the recovery was 95%~106%,the sensitivity of Cd,Bi and Fe was 0.0097,0.19 and 0.050 μg·mL -1 ·1%
