目标转换渐进因子分析法研究化学平衡体系
Studies on the Chemical Equilibria Systems by Target Transformation Evolving Factor Analysis
【摘要】 本文提出了一种计算化学平衡常数的方法——目标转换渐进因子分析.该方法将新近发展起来的渐进因子分析方法与目标转换技术相结合,它不仅可以给出体系的因子数目,而且可以给出各因子的分布趋势.利用该法成功地测定了分析试剂溴邻苯三酚红的逐级解离常数,结果与文献值吻合.
【Abstract】 A method based upon the newly developed algorithm of evolving factor analysis and target transformation technique was proposed for investigation of chemical equilibria. The method was called "Target Transformation Evolving Factor Analysis (TTEFA)". The TTEFA method not only could give the number of factors and the distribution of respective factors, but also could calculate the equilibria constants quantitatively. The method has been applied to study the acid dissociation constants of the analytical reagent Bromopyrogallol Red(BPE). The all of five dissociation constants for BPE were found by the TTEFA method with satisfactory results.
