| Abstract: | 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. |
