摘要
这项工作的目的是探索利用铜交换沸石火山凝灰岩(天然、易于制备和应用)制备新型低成本碳浆安培传感器检测 H2O2 的可能性。利用化学分析、能量色散 X 射线光谱、比表面积、电子显微镜、X 射线衍射光谱和傅立叶变换红外光谱测定了沸石火山凝灰岩的性质。传感器已成功制成,并可在 pH 值为 7、Ag/AgCl/KClsat 的应用电位为 -150 mV 时工作,灵敏度为 0.87 mA M-1,检测限为 10 µM,线性域高达 30 mM H2O2。这些用于检测 H2O2 的良好电分析参数(低检测限和高灵敏度)支持将这些传感器用于检测环境、食品和医疗应用中的多种分析物。
The aim of this work was to explore the possibility of using a Cu-exchanged zeolitic volcanic tuff (which is natural and easy to prepare and apply) for the preparation of a new low-cost carbon paste amperometric sensor for H2O2 detection. The properties of the zeolitic volcanic tuff were determined using chemical analysis, energy-dispersive X-ray spectroscopy, the specific surface area, electron microscopy, X-ray diffraction spectroscopy, and Fourier-transform infrared spectroscopy. The sensor was successfully built and operates at pH 7, at an applied potential of −150 mV Ag/AgCl/KClsat, presenting a sensitivity of 0.87 mA M−1, a detection limit of 10 µM and a linear domain up to 30 mM H2O2. These good electroanalytic parameters for H2O2 detection (a low detection limit and high sensitivity) support the possibility of using these sensors for the detection of many analytes in environmental, food and medical applications.
