摘要

利用羧基化的多壁碳纳米管（MWCNT）修饰氧化铟锡（ITO）电极

表面吸附一层普鲁士蓝（PB）作为电子介体制作一种新型的乙醇传感器。通过循环伏安法、计时电流法对传感器的性能进行表征和研究。结果表明:所制备传感器对乙醇具有明显的电化学活性

线性范围为0.5

0mmol/L

在S/N=3的情况下

检出限为0.07mmol/L（R=0.9968）。该传感器制备简单、经济实用

具有良好的准确性、灵敏度及抗干扰能力。

Abstract

A novel alcohol sensor is made by using indium tin oxides（ITO） electrode

whose surface is modified by carboxylated multi-walled carbon nanotubes（MWCNTs） absorbed a thin Prussian blue film as electron mediator.The sensor’s function had been investigated by cyclic voltammetry and chronoamperometry.The experimental results demonstrate that sensor exhibited a linear range of 0.5

0 mmol/L with a correlation coefficient of 0.996 8.In the case of S/N=3

the detection limit is 0.07 mmol/L.The alcohol sensor not only have the advantages of easy to prepare

economic and practical

but also have good accuracy

sensitivity and anti-interference character.
