Abstract


This paper studied the preparation, characteristics and electrochemical property of a new typical chemical modified platinum electrode coated by the prussian blue analog doped with complex europium ion （Eu-PB）. By the method of cyclic voltammetry （CV） and differential pulse voltammetry （DPV）, the electrochemical behaviors of Ru（bpy）32+、paracetamol（ACOP） and ascorbic acid （AA） on the modified electrode were studied. The results showed that the Eu-PB modified platinum electrode exhibited excellent electrocatalytic oxidation activity for Ru（bpy）32+、ACOP and AA. An accurate and rapid electrochemistry analytical method using a Eu-PB modified platinum electrode for the determination of components in pharmaceutical formulations and soft beverages was developed respectively. Compared with others, those methods demonstrated low detection limits, broad range of concentration and excellent stability. There were three sections on this paper as below:Section one: This part introduced the development and the history, types, preparation, characteristics and applications of the chemically modified electrode coated with PB analog material.Section two: This part reported the preparation and electrochemical property of Eu-PB modified platinum electrode by using cyclic voltammetry （CV） and differential pulse voltammetry （DPV）. The surface material on the modified electrode was characterized by electrochemical impedance spectroscopy , Raman scattering spectroscopy and fluorescence spectroscopy.Section three: This part reported the analytic application of the Eu-PB modified platinum electrode.I : Electrocatalytic oxidation and electrochemiluminescence of Ru（bpy）32+ on the prussian blue analog doped with complex Eu3+-glycine film modified electrodeII: The electrochemical behavior and analysis of ACOP based on application of the prussian blue analog doped with complex Eu3+ film modified electrodeIII: The electrochemical behavior and analysis of AA based on application of the prussian blue analog doped with complex Eu3+-glycine film modified electrode
