Abstract

The nitrate content is a crucial indicator for evaluating water quality and pollution levels, making monitoring essential. In this study, hundreds of nitrate ion-selective electrodes (

{NO}_{3}^{-}

-ISEs) were fabricated using a scalable manufacturing method for in-situ nitrate detection. This study investigated the impact of ion-selective membrane (ISM) geometry (e.g., thickness and surface area of the ISM) on the performance of ISEs. Potentiometric and electrochemical analyses demonstrated that ISEs with thinner ISMs or larger areas could complete their conditioning and achieve a stable potential within 12 h, compared to those with thicker ISMs or smaller areas. In particular, the increase in ISEs area enhanced long-term stability. The practical performance of the

{NO}_{3}^{-} ISEs

were assessed in a simulated soil environment, aquaculture water containing bacteria in an indoor laboratory setting, and subsequently in water runoff from agricultural fields over two weeks, showing high accuracies comparable to those obtained using much more expensive commercial glass sensors.

固态硝酸离子选择性传感器的制造参数优化及其实验室和现场测试

硝酸盐含量是评价水质和污染程度的重要指标，因此监测必不可少。在这项研究中，使用可扩展的制造方法制造了数百个硝酸盐离子选择电极（NO3−-ISEs），用于原位硝酸盐检测。本研究调查了离子选择膜（ISM）几何形状（例如，ISM的厚度和表面积）对离子选择膜性能的影响。电位和电化学分析表明，相对于ISMs较厚或面积较小的ise， ISMs较薄或面积较大的ise可以在12 h内完成调节并获得稳定的电位。特别是，国际货币基金组织面积的增加增强了长期稳定性。NO3−ise的实际性能在模拟土壤环境中进行了评估，在室内实验室环境中对含有细菌的水产养殖水进行了评估，随后在两周内对农田径流进行了评估，显示出与使用更昂贵的商用玻璃传感器所获得的精度相当。

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
