چکیده
|
Electrochemical behaviors of epinephrine and acetylcholine were investigated, using cyclic voltammetry, on the ag-zno modified screenprinted electrode (ag-zno/spe). ag-zno nanoplates showed excellent electrocatalytic activity toward the oxidation of epinephrine and acetylcholine compared with bare spe in 0.1 m pbs. under the optimized experimental conditions, a linear response obtained in the range of 0.13 to 450.00 μm with detection limit of 0.04 μm for epinephrine. ag-zno/spe exhibits good stability, reproducibility and repeatability, and the method has been successfully applied for detection of epinephrine and acetylcholine in their pharmaceutical and biological samples with satisfactory recovery.
