چکیده
|
The acetanilide modified carbon paste electrode (anmcpe) was used for thevoltammetric 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) withthe mixture of graphite powder and silicon oil. cyclic voltammetric study improved thereversibility of the da on the modified electrode. the effect of various experimentalparameters such as acetanilide concentration, scan rate, and ph on the voltammetric responseof da was investigated. under the chosen conditions, the differential pulse voltammetry peakcurrent was found to be linear with da concentration. the detection limit for modifiedelectrode was found to be 6×10-7 m for da determination.
