摘要: 微波等离子体原子发射光谱法(MIPAES)测定碲,前人已作过一些工作[1.2]。本文利用我们建立的微量进样系统[3]与MIPAES联用,对碲的测定进行了研究。实验中发现,加入适量的SnCl2可降低检出限约一个数量级,Te214.3nm的检出限为5ng/mL,同时还研究了碱金属卤化物对碲的测定的影响。

Abstract: In this paper, the determination of tellurium by ETV-MIPwith a new micro sample introduction system was studied. It was shown that the addition of SnCl2 AEScan increase the emission signal of Te at 214.3 nm. The detection limit is shown to be 5.0 ng/mL. The influence of alkali halide in the aqueous solutions with SnCl2 and without SnCl2 on the emission signal of Te 214.3 nm line was studied in some detail.
