火焰原子吸收光谱法测定合金薄膜热电材料中Sb和Te的相对含量

摘要

研究了在室温下用（1+1）HNO3 溶解Sb-Te合金薄膜，用火焰原子吸收光谱法测定Sb、Te的含量。其结果表明，方法准确，可靠，加标回收率为96%—105%，RSD为0.4%—4.4%。%The relative composition measurement of antimony(Sb) and tellurium(Te) was carried out in the flame atomic absorption spectrometry（FAAS）.The antimony tellurid ealloy films was dissolved by(1+1)HNO3 at room temperature.The recovery is 96%—105% and the RSD is 0.4%—4.4%.The method is simple and reliable with high precision and accuracy.
