| Abstract: | This article covers the preparation of a bismuth/alizarin S composite film-coated glassy carbon electrode and the eletrochemical determination of chloramphenicol by cyclic voltammetry and differential pulse voltammetry with the composite bismuth electrode.The new electrode shows an obvious electrocatalytic activity for the reduction of chloramphenicol and presents well-defined,reproducible and sharp signal.Factors influencing the determination performance including the film preparation,scan rate and solutio... |
