分析化学上可以采用催化动力学法对某些微量元素进行测定。这项工作在国外学者中巳广泛进行,迄今为止,能够应用催化动力学法作分析的元素已有二十几咱之多[1].国内学者,近年来也开始在这方面迸行一些工作[2,3].不仅如此,催化动力学法还可以作力研究溶液中络合物平衡的工具[4,5] Analytical chemistry can use catalytic kinetic method for the determination of certain trace elements. This work has been extensively carried out among foreign scholars, and as of now, more than two dozen elements have been applied to the analysis of catalytic kinetics [1]. Domestic scholars have also started to do some work in this area in recent years Furthermore, catalytic kinetic methods can be used as a tool to study the equilibrium of complexes in solution [4,5]
