摘要： 2,2′-联吡啶在金电极上需长达10 h 左右才能达到吸附平衡和有足够量的分子来促进细胞色素 c 的电化学反应.需用长时间浸泡膜转移法,减小因促进剂分子吸附强度的变化而造成的差别.

Abstract: It was found in this paper that only when sufficient amount of promoter molecules are adsorbed on the electrode surface,can the promoter effectively accelerate the electro-chemical reaction of cytochrome c.For a promoter such as 2,2′-bipyridine,whose molecules possess weak adsorption strength on the electrode surface,a prolonged adsorption time, such as 10 hours,is required to attain the adsorption equilibrium with sufficient amout of promoter molecules adsorbed on the electrode surface.Therefore,it is better to use a modified procedure with prolonged dipping time to minimize the differences in promoter effects brought about by variations in the adsorption strength of the promoter molecules.

Key words: bipyridine, cytochrome c, adsorption, promotion
