Abstract

An electrochemical sensor based on the use of CeO2 nanoparticles modified glassy carbon electrode (CeO2/GCE) was prepared and applied for determination of Cu(II) and Hg(II) individually and simultaneously. The differential pulse anodic stripping voltammetry (DPASV) results indicates that the CeO2 NPs based sensor exhibits good electroanalytical performance with two well-resolved voltammetric stripping peaks for Cu(II) and Hg(II). The proposed CeO2 NPs based sensor shows a wide linear range from 10 to 350 mu g/L and a lower detection limit (3o) 2.9 for Cu(II) and 3.3 mu g/L for Hg(II) under optimized conditions. The developed sensor was successfully applied for the quantification of Cu(II) and Hg(II) in real sample matrices, and satisfactory results were obtained.
