摘　　要：检测水中多氯联苯含量传感器由电化学三电极、信号采集及转换电路、单片机和显示单元组成。采用示差脉冲法,在单片机的控制下,为三电极提供-0.3~0.6 V连续变化电压信号,驱动三电极系统中待测液发生氧化/还原反应。该系统实现了对多氯联苯含量的快速检测。Electrochemical immune sensor is used to detect naphthalene content in the water in this system, which is consisted of three-electrode electrochemical system, signal acquisition and conversion circuits, microcontroller and display units.the exciting waveform is differential pulse voltammetry（DPV）, which is generated by the microcontroller, its voltage range is from-0.3 to 0.6 V. The system can achieved quickly the quantitative detection for PCBs content in water.
