玉米素和激动素的伏安行为

Voltammetric Behavior of Zeatin and Kinetin

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Ｃｕ（２＋）、Ｅｕ（３＋）、Ｃｄ（２＋）、Ｚｎ（２＋）的电极还原产生的影响。

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.
