Aniline is widely used raw chemical material in various
industrial processes, such as dye, pesticide and rubber
industrics. It has been suspected asa carcinogen under long-term
exposure. No electrochemical scheme has been developed for
the determination of aniline yet. A severe electrode
faultingproblem from the aniline oxidation hinders the
subsequent electrochemicalreaction. The consequency of the
polymerization reaction decreases thefuther mass transfer
behavior. In current project, we report an electrodesurface
regenerable procedure to remove the faulting polymer on
electrodesurface. By applying a ±1.8 volts pulse train to the
electrode after each electrochemical mesurement, the following
signal can be maintained steadily with a relative standard
deviation 0.62%(n=20). In contract, the electro-chemical signal
decreases 49% from the first determination with a
relativestandard deviation 23.3% after successive twenty
measurement. The estimated detection limit(S/N=3)is 6.48 ppb
(0.05μM) and the linearity of the response is up to 21.3 ppm
(or 165μM with corelation coefficient R=0.9997).
