石墨炉原子吸收光谱法测定稀有金属中镉和钼的报道很少。日本曾使用具有塞曼效应背景校正的石墨炉原子吸收光谱法测定了锆合金中镉和铅。西北有色金属研究院张国瑞等使用配备有HGA-500型石墨炉及程控器的P-E 5000型原子吸收光谱仪进行了锆及其合金中镉和钼的测定试验,结果表明,镉可直接测定、对元素钼则需分离基体元素锆后才能测定。方法简便快速,适合锆及其合金中0·1 ppm以上镉,20 ppm以上钼的
Graphite furnace atomic absorption spectrometry for the determination of rare metals, cadmium and molybdenum rarely reported. Japan has used graphite furnace atomic absorption spectrometry with Zeeman effect background correction for the determination of cadmium and lead in zirconium alloys. Zhang Guorui Northwest Institute of Nonferrous Metal and other equipment equipped with a HGA-500 Graphite Furnace and program-controlled PE 5000 atomic absorption spectrometry zirconium and its alloys in the determination of cadmium and molybdenum, the results showed that cadmium can be directly measured, the element Molybdenum is required to separate the matrix element of zirconium to determine. The method is simple and fast and is suitable for molybdenum in 0.1% cadmium and 20 ppm in zirconium and its alloys
