在分析化学及络合物化学的领域中已广泛采用摩尔比法连续递变法平衡移动法,斜率比法,直线法和三元相图法来测定络合物的组份络合比,但这些方法均不能指出单核或聚核络合物的存在。近年来,国内外已发表了许多文章,运用分光光度法的数据来区别单核与聚核络合物的存在,这些方法中最主要的一种类型是基于稀释对络合物离解度的影响而建立的数学模型。本文所提出的方法虽然也属于这一种类型,然而与其他方法不同的是本文采用比值法(即直接通过数学计算)或直线法(即通过作图判断)求出络
In the field of analytical chemistry and complex chemistry, molar ratio method of continuous shift balance shift method, slope ratio method, straight line method and ternary phase diagram method have been widely used to determine the complex ratio of the complex components, but these None of the methods can indicate the presence of mononuclear or polynuclear complexes. In recent years, many articles have been published both at home and abroad. The use of spectrophotometric data to distinguish the existence of mononuclear and polynuclear complexes, the most important of which is based on the effect of dilution on the degree of complex dissociation The established mathematical model. Although the method proposed in this article also belong to this type, but with other methods is different from this method using the ratio method (that is, directly through the mathematical calculation) or straight line method
