On-chip generated mercury microelectrode for heavy metal ion detection

Author affiliations

Abstract

In this paper, the on-chip generated mercury microelectrode for heavy metal ion detection has been presented. A mercury droplet (∼150 μm in diameter) is on-chip generated to form a microelectrode through the mercury microfluidics control. The mercury microelectrode is used to electrochemically detect the heavy metal ions. The sample solutions with different concentration of heavy metal ions (Pb2+ and Cd2+) have been successfully detected on the mercury droplet microelectrode using the square wave stripping voltammetry.
