石墨炉原子吸收光谱法测定P91钢中Sb的含量

Determination of Sb in P91 Steel by GFAAS

介绍了采用石墨炉原子吸收光谱法测定P91钢中Sb的含量。试样以盐酸、硝酸和高氯酸溶解,通过高氯酸冒烟除去氯化物。将试液移入石墨管中原子化,用Sb无极放电灯作光源,用原子吸收光谱仪于Sb217.6nm波长处测量其吸光度。

This paper introduced the determination of Sb in P91 steel by GFAAS. The sample was dissolved with hydrochloric acid,nitric acid and perchloric acid, and the chloride of it was removed by heating perchloric acid to smoke. The solution was moved into graphite tube and atomized, and then its absorbance was measured by the atomic absorption spectrometer at Sb 217.6nm wavelength using Sb electrodeless discharge lamp as the light source.
