英文摘要: A simple, sensitive and selective sensor based on carbon paste electrode modified by functionalized mesoporous silica material was developed for the electrochemical determination of ceftazidime (CFZ). The functionalized mesoporous silica was synthesized through a self-assembly process using triblock copolymer as template under acidic conditions and then incorporated in the carbon paste electrode as a modifier. This modifier was characterized by transmission electron microscopy, X-ray diffraction and scanning electron microscopy. The oxidation of CFZ was studied on modified carbon paste electrode using cyclic voltammetry, differential pulse voltammetry and electrochemical impedance spectroscopy (EIS). The results show that the oxidation peak current of CFZ on the modified carbon paste...
