Abstract
The fast oxidation of ascorbic acid by Fe(III)benzohydroxamic acid complex [Fe(BHA)3] has been investigated by the stopped-flow technique in aqueous ethanol medium at three pH values (4.6, 7.0, and 9.0). The reaction exhibits a first-order dependence of rate each on [ascorbic acid] and [Fe(BHA)3], obeying Michaelis-Menton kinetics. The rate of the reaction was found to be pH-dependent.
摘要
在水乙醇介质中，于三个pH值（4.6、7.0和9.0）下，采用停流技术研究了抗坏血酸被Fe(III)苯甲酰异羟肟酸络合物[Fe(BHA)₃]的快速氧化。该反应的速率对[抗坏血酸]和[Fe(BHA)₃]均呈现一级依赖性，符合米氏动力学。发现该反应的速率与pH有关。
