采用石墨炉原子吸收测定了高纯硒中12种杂质元素。各元素检出限均在1.99～28.8ng/g之间,测量精度为2.1％～8.1％。并利用“出现温度”的变化将硒对各元素干扰进行了讨论。
Determination of 12 kinds of impurity elements in high purity selenium by graphite furnace atomic absorption spectrometry. The detection limits of all the elements are between 1.99 ~ 28.8ng / g, the measurement accuracy of 2.1% ~ 8.1%. And the use of “temperature change” to selenium on the elements of the interference were discussed.
