聚拉莫三嗪膜修饰玻碳电极的电化学行为及电催化性能研究
Electrocatalysis Properties of Glassy Carbon Electrode Modified with Poly-lamotrigine and Its Electrochemical Behavior
摘要
Abstract
A glassy carbon electrode modified with poly-lamotrigine film (PLTG/GCE) was fabricated. The poly-lamotrigine film was deposited at the glassy carbon electrode by cyclic voltammetry in H2 SO4 solution. The electrode was characterized by alternating current (AC) impedance. NO2 was determined by the differential pulse voltammetry(DPV) using the electrode in KH2PO4 and Na2 HPO4buffer solution. The modified electrode exhibited good electrocatalytic response to the oxidation of nitrite. A good linear relationship was obtained between the anodic peak currents and NO2' concentrations in the range of 9. 6 × 10-6 - 1. 1 × 10-3 mol · L-1 (correlation coefficient r =0. 998 8) with a detection limit of 3. 2 × 10-6 mol · L-1. The proposed method was applied for the determination of NO2- in real water samples with satisfactory results.关键词
