电热石墨炉原子吸收法测定铸铁中微量碲

Determination of Trace Tellurium in Cast Iron by Graphite Furnace Atomic Absorption Spectrometry

本文研究了用石墨炉原子吸收光谱法测定铸铁中微量碲的方法。进行了系统的研究,结果表明此法具有简便,灵敏,准确的特点。用于测定铸铁中微量碲(含量0.x％～0.00x％范围内)结果令人满意。

The determination of trace tellurium in cast iron fay GFAAS has been investigated.lt is sensitive, simple, rapid and accurate.No separation was required. The method proposed can be used for the determination of tellurium ranging from 1011x to 0.x%with satisfactory results, the characteristic content is 6.4x10-11g, the recovery is 93.3 to 100%.
