In this work, we report for the first time the determination
of ethanol by BIA with multiple pulse amperometric detection
using gold as working electrode and 0.5 mol L−1 NaOH as unique
reagent. The proposed BIA method is simple, accurate, rapid
(180 injections h−1) and can be easily used in outside (on-site)
analysis. The sample manipulation requires only a simply dilution
(fuel ethanol) or a manual extraction and further dilution (gasohol)
which can also be easily performed outside of the laboratory. The
proposed electrochemical method detects only ethanol, what can
