一种新型的平面叉指电极传感器的设计与实现
Design and Realization of A Novel Planar Interdigitated Electrode Sensor
摘要
Abstract
With increasingly stringent environmental standards,inorganic salts,especially nitrate as an important symbol of water pollution,have been highly focused by researchers. This paper proposed a new type of planar interdig⁃itated electrode sensor for inorganic ions detection and centered around mechanism of it in electrolyte solution with AC impedance technique and electrode kinetics analysis. An equivalent circuit model for double layer effect and elec⁃trode process were proposed and applied to characterize the responses of impedance and phase over the different fre⁃quency ranges. Meanwhile,experimental results show that planar interdigitated electrode sensor have the ability to distinguish the different concentrations of inorganic salt solution,and the distinct identification of nitrate and phos⁃phate based on the features of impedance spectroscopy and phase spectroscopy was also presented in this work.关键词
