在分析方法实验研究中,近年来发展了一种新的优选法——单纯形法,它可以通过较少次数的实验找出接近最佳的分析条件组合。特别在交互作用复杂,因素较多的场合,此法尤其简便可靠。Michall已用该法来选择萃取浓集和分析Fe(Ⅱ)的最佳条件,获得了满意的结果。在用原子吸收光谱法测定铂、钯、金时,我们利用此法来选择仪器最佳测定条件也获得了满意的结果。并与正交试验法作了比较。 In the experimental study of analytical methods, a new optimization method, simplex method, has been developed in recent years. It can find the near best combination of analytical conditions through a few experiments. Especially in the complex interaction, factors, more occasions, this method is particularly simple and reliable. Michall has used this method to select the optimal conditions for the concentration and analysis of Fe (II) by extraction, and obtained satisfactory results. In the determination of platinum, palladium and gold by atomic absorption spectrometry, we also obtained satisfactory results by using this method to select the optimal measuring conditions for the instrument. And compared with the orthogonal test method.
