中文摘要	a glassy carbon electrode coated with an electrodeposited film of mixed-valent cobalt oxide/cyanocobaltate (co-o/cn-co) enabled hydrazine compounds to be catalytically oxidized at the greatly reduced overpotential and in a wide operational ph range (ph 2.0-7.0). electrocatalytic activity at the co-o/cn-co modified electrode was evaluated with respect to solution ph, film thickness, supporting electrolyte ions, potential scan rate, operating potential, concentration dependence and other variables. the co-o/cn-co film electrode was completely compatible with a conventional reversed-phase liquid chromatographic (rp-lc) system. practical rp-lc amperometric detection (rp-lcec) of hydrazines was performed. a dynamic linear response range over three orders of magnitude and a detection limit at the pmol level were readily obtained. the co-o/cn-co film electrode exhibited excellent electrocatalytic stability in the flowing streams.
