研究了杂多酸阴离子α- P2 W1 7O1 0 -61 修饰电极的制备及其化学性质。α- P2 W1 7O1 0 -61 修饰电极对 Br O-3 具有催化作用。催化电流 ΔIp 与 [Br O-3 ]在 7.0× 1 0 -6～ 1 .0× 1 0 -4mol/ L范围内呈良好线性关系。用此电极测定了天然水中 Br O-3 的含量 ,结果令人满意
The preparation and the chemical properties of the heteropolyacid anion α-P2 W1 7O1 0 -61 modified electrode were studied. The α-P2 W1 7O1 0 -61 modified electrode has a catalytic effect on Br O-3. The catalytic current ΔIp showed a good linear relationship with [Br O-3] in the range of 7.0 × 10 -6 ~ 1 .0 × 10 4 mol / L. The content of Br O-3 in natural water was measured with this electrode, and the result was satisfactory
