本文用分光光度法研究了碱性介质中二过碘酸合铜（Ⅲ）配离子氧化氨基乙酸的反应动力学。实验结果表明反应对Ｃｕ（Ⅲ）是准一级。表观速率常数ｋｏｂｓ随着氨基乙酸浓度的增加而增大，随着〔ＯＨ－〕的增大而增大，但随着〔ＩＯ－４〕的增大反而减小；且发现１／ｋｏｂｓ对〔氨基乙酸〕和１／ｋｏｂｓ对〔ＩＯ－４〕有线性关系。据此提出了一种含有前期平衡的反应机理，推出了一个能够解释全部实验事实的速率方程式，求得了速控步骤的速率常数ｋ，并给出了相应的活化参数。
In this paper, the reaction kinetics of glycine oxidation with copper (Ⅲ) diperiodate in alkaline medium was studied by spectrophotometry. The experimental results show that the reaction is quasi-one for Cu (Ⅲ). The apparent rate constant kobs increases with increasing glycine concentration, increases with [OH-] but decreases with increasing [IO-4], and it is found that the ratio of 1 / kobs to [Glycine] and 1 / kobs have a linear relationship [IO-4]. Accordingly, a reaction mechanism with pre-equilibrium is proposed and a rate equation which can explain all the experimental facts is introduced. The rate constant k of the quick control step is obtained and the corresponding activation parameters are given.
