Surface Modification of Glassy Carbon Electrode for Electrochemical Selective Determination of Heavy Metal Ions

摘要

Owing to its physical and chemical properties, glassy carbon has become an interesting and widely applied electrode material. It exhibits a rather low oxidation rate and a rather high chemical inertness which, together with very small pore sizes and a small gas and liquid permeability, make glassy carbon a convenient inert electrode. Introduction of newer methods and modification of the existing analytical method for the determination of pollutants constitute a rule in green chemistry. Nowadays, modified methods highly contribute to the development of sensors for pollutants and hazard materials. In this chapter, the characterization and electrochemical activation will be firstly summarized. Then, strategies for glassy carbon electrode surface modification were detail discussed. In the end, the recent application of modified glassy carbon electrode in heavy metal ions determination were summarized.
