本文将双显色双波长分光光度法成功地应用于三组份、四组份同时测定,拟定了一种新颖的处理无机多组份体系的方法。经实验证实,通过适当选择两个显色体系和最佳波长对组,该法不仅能有效地排除干扰,而且可明显提高测定灵敏度,在实践上具有更大的适应性。 In this paper, dual color dual-wavelength spectrophotometry was successfully applied to three components, four components simultaneously measured, to develop a novel method of processing inorganic multi-component system. The experiment confirmed that by appropriate choice of two color system and the best wavelength pair group, the method can not only effectively eliminate the interference, but also significantly improve the sensitivity of the assay, in practice, has greater flexibility.
