摘要：
A G/PtNP-Chi modified electrode was prepared by immobilizing Pt-nanoparticles in a chitosan film The investigation of the influence of the experimental conditions (scan rate, frequency, pH) on the electrochemical behaviour of epinephrine (EP) was realized by both cyclic and square-wave voltammetry. The electrochemical parameters and analytical parameters like high sensitivity and low detection limit of the G/PtNP-Chi modified electrode make it very suitable for accurate determinations in real samples of pharmaceutical formulation.
