摘要：

The effect of two different techniques for the preparation of the surface of a gold electrode on the sensitivity of the stripping voltammetric determination of mercury(II) was studied. The electrochemical polishing of the electrode in a solution containing thiourea, sulfuric acid, and ammonium thiocyanate lowered the detection limit for mercury down to 2 ng/L and improved the reproducibility of mercury anodic peaks.
