Fe^(3+)、碲对硒的氢化物化学干扰机理的实验研究

Experimental Study on the Mechanism of Chemical Interference of Tellurium with Selenium by Hydride AFS in the Presence of Fe 3+

本文实验研究了硒的氢化物发生中Ｆｅ３＋与碲的协同反应对原子荧光法测硒的化学干扰。首次提出了相对Ｆｅ３＋含量ｍ（Ｓｅ）ｍ（Ｔｅ）ｍ（Ｆｅ２Ｏ３）达到５．０ｍｇ时，可以有效消除干扰，探讨了有关反应机理。

This paper describes the coaction of tellurium and Fe 3+ on selenium in hydrogenization by experiment.The experimental result proved that certain amount of Fe 3+ can eliminate the interference.Under optimum conditions,the reaction mechanism was discussed.
