摘要
本文报道了一种电流型银离子玻璃固态电解质 NO2 气敏传感器 ,该传感器可在室温下工作 ;响应及恢复速度较快 ;能检测低达 0 .5ppm的 NO2 气体浓度 ;在 0～ 10 0 ppm范围内与被测气体浓度具有线性关系 ;基本消除了记忆效应且不受空气及氧气的影响。本工作为研制和开发小型、廉价、适用于工业废气和汽车尾气等污染源的在线实时检测 NO2
This paper deals with an amperometric sensor that was constructed using a novel Ag +ion conducting glass system as the solid electrolyte for the detection of NO 2 gas. The sensor works at room temperature, with very fast response and recovery rate. It can detect NO 2 even at the concentration of 0.5ppm.There is linear ralation between the current value detected and the NO 2 concentration from 0 to 100 ppm. It has no memory effect. It was hardly affected by air or O 2.The result will lay a foundation for developing the instrument that is smaller size, cheap and that is applied to on line detection of NO 2 from industrial waste and vehicle exhaust.
