地质样品中微量碲测试方法研究

Research on Testing Methods of Trace Tellurium in Geological Samples

地质样品经由硝酸、氢氟酸、高氯酸三酸溶解,用盐酸溶液提取溶解样品,加入一定量的铁盐用以掩蔽干扰。采用断续流动氢化物原子荧光光谱法测定样品中元素碲的含量,并且在试验过程中找出该方法测定碲元素的最佳条件。

The sample was dissolved by nitric acid, hydrofluoric acid and perchloric acid, then dissolved sample was extracted by hydrochloric acid solution, and molysite was added to mask interferences. Tellurium element in the sample was determined by intermittent flow hydride generation atomic fluorescence spectrometry. The test determining conditions were found out.
