摘要: 玉米素和激动素在0.1mol/L的醋酸-醋酸钠底液里能还原,产生很好的极谱峰,检测灵敏度可达2.5×10-8mol/L,峰电位分别为-1.18V和-1.17V(对Ag/AgCl).测定了电极反应决定步骤的anα和电化学反应的标准速率常数ks.研究了它们对Cu2+、Eu3+、Cd2+、Zn2+的电极还原产生的影响。

关键词: 玉米素, 激动素, 伏安法

Abstract: In 0.1 mol/L HAc-NaAc solution, the polarographic reduction waves of zeatin and kinetin have been obtained.The electrode process was also disscussed.In the presence of zeatin or kinetin, the reduction potentials of some metalic ions were shifted.

Key words: Zeatin, Kinetin, Voltammetry
