A chromatographic method, using amperometric detection, for the sensitive determination of six representative mutagenic amines was developed. A glassy carbon electrode (GCE), modified with multiwall carbon nanotubes (GCE-CNTs), was prepared and its response compared to a conventional glassy carbon electrode. The chromatographic method (HPLC–GCE-CNTs) allowed the separation and the determination of...
In this paper, l-cysteine/graphene–CS/GCE (l-cys/GR–CS/GCE) was prepared successfully, and its electrochemical properties were characterized by cyclic voltammetry (CV) and electrochemical AC impedance. Moreover, the electrochemical behaviors of Cd2+ and Pb2+ on the proposed electrode were studied by differential pulse anodic stripping voltammetry (DPASV). Experimental parameters, such as the deposition...
