摘要
采用自吸石墨炉原子光谱法测定汽水中镉的含量,绝对灵敏度为5×10^-12g,平均回心率为95.5%,变异系数3.7%,准确度高,有具有选择性好、方便、快速等优点。
The content of cadmium(Cd) in soda water was detected by means of atomic spectral method with auto-absorption graphitic oven.Absolute sensitivity was 5×10^(-12)g,aver- age recovery was 95.5%,this method include hish accuracy,hish selectivity,convenience and ra- pidity.
