| 摘 要： | 研究了纳米La(OH)3修饰电极的制备及其对邻苯二酚和对苯二酚的电催化作用。讨论了支持电解质种类、酸度等对邻苯二酚和对苯二酚伏安响应的影响,获得了较为优化的实验条件。在0.1mol/LPBS(pH7.0)中,采用示差脉冲伏安测定邻苯二酚和对苯二酚,其浓度与氧化峰电流线性关系良好。共存的多种金属离子、抗坏血酸及等量的苯酚等不干扰测定。该电极用于模拟废水样中邻苯二酚和对苯二酚的测定,结果令人满意。

| Abstract: | The La(OH)3 nanoparticles modified glassy carbon electrode was fabricated and its electrocatalytic activity for the oxidation of of o-benzenediol and p-benzenediol was investigated. The effect of the type and acidity of electrolytes and the optimum conditions for the simultaneous determination of o-benzenediol and p-benzenediol were studied. In 0.1 mol/L PBS(pH 7.0)the concerntration of o-benzenediol and p-benzenediol are linearly with their peaks currents respectively in differential pulse voltammetry. Various metal ion, ascorbic acid and phenol have nearly no effect on the determination. The modified electrode can be used in the determination of o-benzenediol and p-benzenediol in imitative waste water. |
