It has been shown by photopolarographic method that under stationary illumination chlorophyll-photosensitized reduction of dyes with ascorbic acid proceeds according to the first kinetic order. Rate constants of photoreduction of vitamin K3, methelene red, safranin-T and methylviologen were found in the course of sensitization which proceeded by oxidative and reduction mechanisms. Similarity of kinetics at both sensitization mechanisms was shown. Results obtained by polarographic and spectroscopic methods were compared.
光极谱法表明，在固定光照下，叶绿素用抗坏血酸对染料进行光敏还原反应按一级动力学进行。在通过氧化和还原机制进行的敏化过程中，发现了维生素K3、亚甲基蓝、番红T和甲基紫精的光还原速率常数。两种敏化机制下的动力学相似性得到了体现。对极谱法和光谱法获得的结果进行了比较。
