摘　　要：在硝酸银(AgNO 3)溶液中,采用电化学沉积法制备纳米银。通过循环伏安法(CV)和阻抗谱(EIS)对其电化学性能表征。最后利用合成的物质制备重金属离子电化学传感器,实现了对铅离子[Pb(Ⅱ)]和铜离子[Cu(Ⅱ)]的检测,其检测限分别为0.13μmol·L-1和0.21μmol·L-1,结果表明纳米银可作为制备电化学重金属离子传感器材料之一。Dendritic silver nanoparticles were prepared by electrochemical deposition method in a single AgNO 3 solution.The electrochemical properties were characterized by cyclic voltammetry(CV)and impedance spectroscopy(EIS).Finally,the electrochemical sensors of heavy metal ions were prepared with the synthesized nano-silver,and the detection limits of Pb(II)and Cu(II)were 0.13μmol·L-1 and 0.21μmol·L-1 respectively.The experimental results proved that dendritic nano-silver as one of the materials could be used for the preparation of electrochemical heavy metal ion sensors.
