Abstract :
The acetanilide modified carbon paste electrode (ANMCPE) was used for the
voltammetric response of dopamine (DA) in an aqueous phosphate buffer solution (PBS).
Modified carbon paste electrode was prepared by grinding the 5 mg of acetanilide (AN) with
the mixture of graphite powder and silicon oil. Cyclic Voltammetric study improved the
reversibility of the DA on the modified electrode. The effect of various experimental
parameters such as acetanilide concentration, scan rate, and pH on the voltammetric response
of DA was investigated. Under the chosen conditions, the differential pulse voltammetry peak
current was found to be linear with DA concentration. The detection limit for modified
electrode was found to be 6×10-7 M for DA determination.
