Abstract
Abstract: Heavy metal ions have great hazard to human beings. The development of low-cost, mass-produced electrochemical sensors based on screen-printing technology has attracted considerable attention in recent years. In this paper we fabricated the Screen-printed carbon electrodes(SPCE) and realized the simultaneous detection of heavy metal ions(Cu,Pb,Zn) complied with the use of differential pulse anodic stripping voltammeter(DPASV) and optimized the detection conditions. The electrodes had satisfying sensitivity and precision, the detectable concentration reached ppb level
