Silver Nanorod Array Electrodes and their Application for Detection of Low Concentration Chloropropanol in Aqueous Media
Silver nanorod array electrodes were prepared by a facile method. The characters of silver nanorod arrays were tested by SEM and XRD. The electrochemical activity of this electrode was tested in the 0.1 mol/L NaClO4aqueous solution using chloropropanol as analyte by electrochemical methods. The results of cyclic voltammetry show that silver nanorod array electrodes are good detector for low concentration chloropropanol in aqueous media and display a distinct reduction peak. It is more sensitivity than the bulk Ag electrode. Cyclic voltammetry and Warburg impedance measurements show that the action process between electrode and chloropropanol was controlled by the diffusion and the reaction is totally irreversible. In short, silver nanorod array electrodes show great potential in the determination of trace chloropropanol.
