摘　　要：随着生物无机化学研究的深入,生物体中微量元素的分析日益重要。目前,生物体中微量元素的分析方法主要是火焰光度、原子吸收、原子发射及荧光分析等。发射光谱分析具有可同时测定多种元素的优点。但是,无论使用何种方法,生物试样的基体效应是值得注意的。我们在用发射光谱法分析出物体试样时也发现。The effects of eight different amino acids on the intensity of elemental spetcral lines in the determination of trace elements of biological samples by AES are investigated. The results demonstrate that the effect of cystine is the most apparent because it inhibits and delays the evaporation of elements, therefore, decreases the intensity of spectral lines. The methods for eliminating and reducing the effects of organic matric were examined and discussed.
