| Hydrazine has implications in soil and ground water contamination and has been identified as a carcinogen that affects liver and kidney functions. Modified electrode surfaces have many applications, including the development of sensors/biosensors and the electrocatalysis of electrochemical reactions. Cyclic voltammetry was used to electropolymerize ruthenium bis(1,10-phenanthroline)(4-methyl-4'vinyl-2,2'-bipyridine) onto glassy carbon electrodes to create a multi-layered thin film. An automated flow injection analysis (FIA) system was developed for routine determination of hydrazine concentration based on the thin film. Reproducable measurements were obtained for sample volumes of 25-75 uL, with a linear calibration response from 1 ppm- 2000 ppm. |
