介绍了间接法用火焰原子吸收光谱测定硅元素 ,硅在 4～ 12 μg ml呈现良好的线性关系。钼检出限 :0 .0 0 8μg ml;方法精密度RSD <3%。
The indirect method was used to determine the elemental silicon by flame atomic absorption spectrometry. The linear relationship between silicon and 4 ~ 12 μg ml showed a good linear relationship. Molybdenum detection limit: 0 0 8μg ml; method precision RSD <3%.
