| 摘 要： | 制备了十六烷基三甲基溴化铵-氧化钕纳米修饰电极。用循环伏安法和示差脉冲伏安法研究了NO2-在该修饰电极上的电化学行为,结果表明,该修饰电极对NO2-的氧化具有良好的电催化能力,NO2-的氧化峰电流与其浓度在3.33×10-8～1.04×10-6mol/L范围内呈现良好的线性关系,检测限为9.86×10-9mol/L(S/N=3)。此外,该修饰电极具有良好的重现性和稳定性。本方法可用于NO2-实际样品的测定。

| Abstract: | We presented a hexadecyltrimethyl ammonium bromide-neodymium oxide modified glassy carbon electrode.The electrochemical behaviors of nitrite at the modified electrode were investigated by cyclic voltammetry,and the results indicated that the modified electrode exhibited an obviously electrocatalytic activity towards the oxidation of nitrite.The differential pulse voltammetric response was linear with the concentration of nitrite in the range of 3.33×10-8～1.04×10-6 mol/L with the detection limit of 9.86×10-9 mol/L(S/N = 3).In addition,the modified electrode has exhibited favorable reproducibility and good long-term stability,and has been successfully used to determine nitrite in samples with satisfactory result. |
