Abstract
A simple, accurate and fast (180 injections h(-1)) batch injection analysis (BIA) system with multiple-pulse amperometric detection has been developed for selective determination of ethanol in gasohol and fuel ethanol. A sample aliquot (100 μL) was directly injected onto a gold electrode immersed in 0.5 mol L(-1) NaOH solution (unique reagent). The proposed BIA method requires minimal sample manipulation and can be easily used for on-site analysis. The results obtained with the BIA method were compared to those obtained by gas-chromatography and similar results were obtained (at 95% of confidence level). Published by Elsevier B.V.Entities:
