Abstract

The gold nanoparticles@carbonaceous microspheres (Au@CMSs) and Au@CMSs modified glassy carbon electrode (GCE) were prepared. The Au@CMSs modified GCE was further examined for possible sensitive detection of mercury ions (Hg(II)) in an aqueous solution by square wave anodic stripping voltammetry (SWASV). The excellent performance was found in the stripping analysis of Hg(II) in 0.1 mol•L^-1 NaAc-HAc(pH=5.0) with a sensitivity of 25.863 A•(mol•L^-1)^-1 and a detection limit of 3.69×10^-8 mol•L^-1 based on the 3σ method.
