看了贵刊1986年第一期《用分光光度法测定络合物真正组成及其稳定常数的一种新的作图法》一文后,感到有些方面需要进行商酌。 (一)作者认为他们提出了一种测定配合物真正组成及其稳定常数的新的数学模型和新的图解法。笔者认为他们的方法在本质上完全是一种最古老的尝试法。通常,在测得配合物MmBn的组成比m/n之后,采用稀释法进行实验,再根据配合平衡方程式,即可得到K=n~n·〔(1-a)C_M〕~(m+n)a~(-1)C_M~(-1)m~(1-n),即作者原文中的式(9)。式中a为配合物的形成率。利用式(9),在满足约束条件m/n的情况下,只要尝试
After reading the first issue of your magazine in 1986, “A New Mapping Method for Determining the True Composition and Stability Constants of Complexes by Spectrophotometry”, I feel that some aspects need to be considered. (A) The authors consider that they have proposed a new mathematical model and a new graphical method for determining the true composition and stability constants of complexes. The author thinks their method is by nature completely the oldest attempt method. In general, after the composition ratio m / n of the complex MmBn is measured, the experiment is carried out by the dilution method, and then K = n ~ n · [(1-a) C_M] ~ (m + n ) a ~ (-1) C_M ~ (-1) m ~ (1-n), which is the formula (9) in the author’s original text. Where a is the formation rate of the complex. Using (9), if the constraint m / n is satisfied, just try
