摘要We report a novel and facile gold microelectrode array (Au MEA) for the determination of trace Cu2+ by differential pulse anodic stripping voltammetry (DPASV). The gold microelectrode array was fabricated by a multi-step micro-fabrication approach combining sputtering for the deposition of metals and the dielectric material (SiO2) on the surface of a silicon wafer and photolithography for the definition of the geometry of the electrode. Due to the rapid mass transporting and low background current of gold microelectrode array, low detection limit (1.3 pM) and wide linear range (10-150 pM) can be obtained for the determination of Cu2+. The practical application of the proposed electrode has been carried out for the determination of trace level of Cu2+ in real seawater sample.
