The study discussed in this work was developed
to determine trace caffeine using square wave
anodic stripping voltammetry (SWASV). We found
that at the optimized conditions and for a 1.4 V
anodic peak current, the voltammetric
concentration effects were comparable to that of
common electrodes, and that the carbon fiber
microelectrode (CFME) is more sensitive than
other electrodes. With the CFME, two working
ranges of 0.5-10 and 20-300 mgL-1 were obtained.
The relative standard deviation of 50.0 mgL-1
was found to have been 0.01 % (n = 12) at the
optimum conditions, and the detection limit
(S/N) attained was 45 ugL-1 (2.310-8 M). The
developed method was applied to the
determination of the caffeine content of popular
drinks and in vivo organs at real.
