电热原子吸收中涂层石墨管、基体改进剂及酸对锗吸光度的影响

The influence of coated graphite tubes,matrix modifiers and acids on the absorption of Ge determined by EAAS

本文对电热原子吸收测定锗时石墨管的种类、基体改进剂及酸的影响进行了试验，确定了满足微量锗测试的条件。但该方法对分析条件要求苛刻，条件稍有改变即导致较大的偏差。

The kinds of graphite tubes, the influence of matrix modifiers and acids are studied when trace germanium is determined by electrothermal atomic absorption spectrometry.The factors of determination of Ge are defined.But this method demands strict determination conditions. A slight variation of determination conditions will result in obvious deviation, which may help explain the large difference in analytical data of determination of Ge in present literature.
