摘　　要：本文提出了用碘离子选择性电极间接测定联氨的方法,其检测下限为5×10^(-5)mol/L。对常见的干扰物质只需进行简单的酸化即可进行测定。This paper describes an indirect method for the determination of trace diamide with a detection limit of 5×10^(-5)mol/L using iodine ion-selective electrode. As for the common reductive interferences, the determination of trace diamide could be carried out with a simple acidation under normal conditions.
