Improved Electrochemical Detection of Zinc Ions Using Electrode Modified with Electrochemically Reduced Graphene Oxide

Original language description

Increasing urbanization and industrialization lead to the release of metals into the biosphere,nwhich has become a serious issue for public health. In this paper, the direct electrochemical reductionnof zinc ions is studied using electrochemically reduced graphene oxide (ERGO) modified glassyncarbon electrode (GCE). The graphene oxide (GO) was fabricated using modified Hummers methodnand was electrochemically reduced on the surface of GCE by performing cyclic voltammograms fromn0 to 1.5 V. The modification was optimized and properties of electrodes were determined usingnelectrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The determination ofnZn(II) was performed using differential pulse voltammetry technique, platinum wire as a counternelectrode, and Ag/AgCl/3 M KCl reference electrode. Compared to the bare GCE the modified GCE/ERGO shows three times better electrocatalytic activity towards zinc ions, with an increase ofnreduction current along with a negative shift of reduction potential. Using GCE/ERGO detectionnlimit 5 ng mL 1 was obtained.
