Abstract

Purpose A novel semiconducting macromolecule-polyperylene tetraamide (PPTI) was first synthesized with a simple method using 3, 4, 9, 10-perylene tetracarboxylic acid (PTCA) and hydrazine hydrate (N2H4). Design/methodology/approach The Ag nanoparticle was doped on the surface or inside of the PPTI film to obtain a highly sensitive hydrazine sensor-Ag/PPTI, which was synthesized within one step. The structure of Ag/PPTI was characterized through various techniques such as Fourier transform infrared (FT-IR), thermogravimetric analyzer (TGA), X-ray diffraction (XRD), X-ray photoelectron spectroscopy measurements (XPS) and scanning electronic microscopy (SEM). Findings According to cyclic voltammetry results, Ag/PPTI/GCE indicated good electrocatalytic activity toward the oxidation of hydrazine. The amperometric detection of hydrazine was then applied on Ag/PPTI/GCE. It exhibited a wide linear range from 0.05 to 50 µM, a low detection limit (S/N = 3) of 0.05 µM and high sensitivity of 0.45 µA/(µM•cm2). Originality/value In authors’ perception, this approach emerges as an effective technique for developing efficient chemical sensors for environmental pollutants.

基于新型Ag Nps/Ppti膜的高灵敏度电化学传感器检测肼

目的以3，4，9，10苝四羧酸（PTCA）和水合肼（N2H4）为原料，采用简单的方法合成了一种新型半导体大分子聚亚乙基四酰胺（PPTI）。通过傅立叶变换红外光谱（FT-IR）、热重分析仪（TGA）、X射线衍射（XRD）、X光电子能谱（XPS）和扫描电子显微镜（SEM）等技术对Ag/PPTI的结构进行了表征，Ag/PPTI/GCE对肼的氧化具有良好的电催化活性。然后在Ag/PPTI/GCE上进行肼的安培检测。它表现出从0.05到50的宽线性范围 µM，0.05的低检测限（S/N=3） µM和0.45的高灵敏度 µA/（µM•cm2）。独创性/价值在作者看来，这种方法是开发高效环境污染物化学传感器的有效技术。
