摘要：

Electrochemical behavior of ferrocene (FeCp) in a single tri-n-butyl phosphate microdroplet (diameter = approximately 20 mum) dispersed in water was studied by a new method of laser trapping-electrochemistry-spectroscopy. Mass transfer of FeCp and ferrocenium ion (FeCp+) across the droplet-water interface accompanied by electrolysis of FeCp in the droplet was directly measured and analyzed. The results were discussed in terms of a distribution reequilibrium of FeCp across the interface, which was spectroscopically supported by fluorescence quenching of 9,10-diphenylanthracene by FeCp in the droplet.
