聚苯胺—H5PMo9V3O40修饰电极的制备及电化学行为

THE PREPARATION AND ELECTROBEHAVIOR OF POLYANILINE HERTERPOLYACID MODIFIED ELECTRODE

制得了一种新型的杂多酸掺杂聚苯胺修饰电极。将杂多酸与苯胺的硫酸溶液混合共聚得到掺杂杂多酸的ＰＡ膜修饰电极，研究表明聚乙撑氧噻吩—Ｈ５ＰＭｏ９Ｖ３Ｏ４０修饰是电极在酸性溶液中对ＢｒＯ３的还原有催化作用。

The preparation and eletrobehavior of polyaniline herterpolyacid modified electrode was investigated and the electrocatalytic reduction of KBrO 3 on the electrode was discribed.The polyaniline heterpolyacid exercises catalysis on the reduction of the bromate ions,at the concentration range of 1 0×10 -5 ～5 0×10 -2 mol/L,and the catalytic reduction current is liner with the concentration of the bromate ions.This modified electrode can be used to indicate the bromate ions.
