肾上腺素电氧化生成肾上腺素醌的反应动力学

Electrochemical Oxidation Reaction Kinetics of Adrenaline to Adrenalinequinone

使用以铂片为工作电极的长光程薄层电化学池,采用单电位阶跃计时吸收法测定了1.0 mol.L-1H2SO4和冰醋酸中,肾上腺素电氧化生成肾上腺素醌的动力学参数.实验结果表明:肾上腺素在1.0 mol.L-1H2SO4介质中比在冰醋酸中容易被氧化.

The electrochemical oxidation reaction kinetics parameters of adrenaline to adrenalinequinone in 1.0 mol·L^-1H2SO4 and glacial acetic acid were determined, using single potential step chronoabsormetry based on a long optical path thin layer electrochemical cell with a plug in platinum working electrode. The result indicated that the electrochemical oxidation of adrenaline is easier in 1.0 mol·L^-1H2SO4 than that in glacial acetic acid.
