测定络合物真正组成的目的、意义以及用分光光度法来判别单核与聚核络合物的方法等,文献中已有报导。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。本文提出的方法虽然也是属于这一类型的,然而与其不同的是,此法是把不稳定常数K当作诸多自变量的函数而建立的一种新的数学模型,由此可推出一个不定方程式,求解便可得到络合物的真正组成及其稳定常数。本法推导严格,应用简便,结果准确。 Determination of the true composition of the complex purpose, significance and spectrophotometry to determine mononuclear and polynuclear complex methods, has been reported in the literature. The most important of these methods is a mathematical model based on the effect of dilution on the degree of complex dissociation. Although the method proposed in this paper is also of this type, the difference is that this method is a new mathematical model established by taking the unstable constant K as a function of many independent variables, thus an indefinite equation , You can get the true composition of the complex and its stability constants. This law is derived strictly, the application is simple and the result is accurate.
