Silica-supported silver picrate was used as an off-line, precolumn derivatization reagent for ethylene dibromide (EDB). Two products were obtained, the ratio of which, as a function of reaction conditions, is characteristic of EDB. The derivatives were monitored with UV, reductive electrochemical, and photolysis/oxidative electrochemical detection. Sub-parts-per-billion detection limits were obtained. The method was used to quantitate EDB in leaded gasoline, and the results were confirmed with gas chromatography with electron capture detection (GC/ECD). The method was further validated with a single blind analysis of spiked EDB in gasoline. This is the first report of an HPLC method for EDB.
