摘要: 应用循环伏安法研究了芦丁碳纳米管修饰玻碳电极(Rt-MWNT/GC)的电化学行为及其对肼的电催化氧化.实验表明,该修饰电极能使肼的氧化电位降至260 mV附近,表现出良好的电催化作用.安培法测得催化电流与肼浓度在2.5×10-6~1.0×10-4 mol·L-1范围内呈线性关系,检出限5×10-7 mol.L-1.

Abstract: The electrochemical behavior and electrocatalytic oxidation of hydrazine on rutin multiwall carbon nanotubes modified glassy carbon electrode were studied by cyclic voltammetry.The experimental results indicated that the electrode exhibits good electrocatalytic activity to hydrazine at a reduced oxidation potential of 262 mV.The amperometric response of the modified electrode showed linear increase after successive addition of hydrazine in the concentration range of 2.5×10-6~1.0×10-4 mol·L-1 with a detection limit of 5×10-7 mol·L-1.
