摘要: 利用紫外吸收光谱法结合计算机模拟研究了肾上腺素(Adin)在Cu(Ⅱ)离子催化下,用H2O2氧化产生肾上腺素红(Adorn)及其进一步反应的动力学。考察了有关反应的速率随Adin的初始浓度、Cu(Ⅱ)高子浓度和H2O2浓度的变化情况。并提出有关反应可能的机理,半定量地解释了相应的动力学行为。

Abstract: Using the ultra-violet absorption spectrometry in connection with the computer simulation, the oxidation reaction kinetics of adrenaline and adrenochrome formed with H2O2 in Cu (Ⅱ) existing as a catalyst has been studiedThe change of reaction rates as regard to the formation and oxidation of adrenochrome with the change of the initial concentrations of adrenaline, Cu (Ⅱ) and H2O2 has been examined, tooFor this reaction, there may be two consecutive steps-Adrenaline→Adrenochrome→other productsThe kinetic laws of these two steps are 05order and first order for adrenline and for adrenochrome, respectively.

Key words: Adrenaline, Adrenochrome, Oxidation
