高纯锡中杂质元素的定量分析,国内外采用了质谱法、中子活化法、化学光谱法、比色法、原子吸收法、极谱法等。直接光谱法测定纯度为99.99～99.999％的锡中杂质元素的方法未见报导。在高纯锡生产过程中,常需分析铅、铜、铋、锑等元素。我们在直接光谱测定锡中铅、铜、铋、银的控制分析经验基础上,应用正交试验法安排实验程序,对影响谱线黑度的电流强度、电极形状、光栏、狭缝诸因素进行了研究,取得了
High purity tin in the quantitative analysis of impurity elements, both at home and abroad using the mass spectrometry, neutron activation, chemical spectroscopy, colorimetry, atomic absorption spectrometry, polarography and so on. The direct spectroscopic method for the determination of impurity elements in tin with a purity of 99.99-99.999% has not been reported. In the high-purity tin production process, often need to analyze lead, copper, bismuth, antimony and other elements. Based on the direct spectroscopic analysis of the control analysis of lead, copper, bismuth and silver in tin, the orthogonal test was used to arrange the experimental procedure. The influences of current intensity, electrode shape, light bar and slit A study has been made
