Amino-functionalized mesoporous silica modified glassy carbon electrode for ultra-trace copper(II) determination

NH2-MCM-41 modified glassy carbon electrode was prepared and it exhibited enhanced anodic stripping response toward Cu (II), which could result from the large surface area of MCM-41 and the good chelating ability of amine-group. The as-constructed electrochemical sensor showed excellent analytical properties in the determination of Cu2+ and was successfully used for real sample assays.
