本文用氢化物发生-原子吸收法研究了一种锗的灵敏的测定技术。它以一种T型电热开缝石英管为原子化器,在10ml 0.10mol/L的HP_3O_4介质中含0.4μg锗时,11次测定的相对标准偏差为2.9％,检出限(S/N=2)为2.4ng。
In this paper, a method of hydride generation-atomic absorption spectrometry for the determination of germanium has been investigated. The relative standard deviation of 11 determinations was 2.9% with 0.4μg germanium in 10ml 0.10mol / L HP_3O_4 medium. The detection limit (S / N = 2) is 2.4 ng.
