摘　　要：以玻碳（ＧＣ）电极为基体制备２∶１８－硫钼杂多阴离子薄膜修饰电极（简称Ｓ２Ｍｏ１８修饰电极）。A monolayer of 2∶18-molybdodisulfate heteropolyanion was modified on a glassy carbon electrode by cyclic potential scanning or simple adsorption in a solution of CH 3CN (φ=95%) containing 9.0×10 -5 mol·L -1 S 2Mo 18 and 0.12 mol·L -1 HClO 4. Cyclic voltammetry was used to study the electrochemical behavior of S 2Mo 18 and S 2Mo 18 film modified electrode. The experimental results show that the modified electrode has high stability and redox activity. The electrocatalytic effect of the modified electrode on iodate anion in a water-organic solution was described.
