研究了锡锌喷金丝中铁含量的测定方法,对原子吸收光谱法测定锡锌喷金丝中铁的各项操作条件进行了试验,试样经盐酸-过氧化氢分解,以盐酸-氢溴酸挥发排锡,在5%的盐酸介质中,采用火焰原子吸收光谱法测定锡锌喷金丝中0.0020%~0.050%铁含量。
The method for the determination of iron content in tin-zinc sprayed gold wire was studied. The operating conditions of iron in zinc-zinc sprayed gold wire were tested by atomic absorption spectrometry. The sample was decomposed by hydrochloric acid-hydrogen peroxide and hydrochloric acid-hydrobromic acid Volatile tin row, in 5% hydrochloric acid medium, the flame atomic absorption spectrometry tin zinc spray gold 0.0020% ~ 0.050% iron content.
