Abstract:
Ammonia classified as one of the hazardous chemical to environment as well as human being. Therefore, monitoring the ammonia in air is a matter of concern. There are several methods to detect the ammonia gas including Nessler’s reagent photo ionisation detector etc. Because of the carcinogenic property of Nessler’s reagent it is not advisable to sense ammonia gas. Photo ionization detector and other electronic sensors have high sensitivity but because of the corrosive nature of ammonia gas they are of short life span. In this work we fabricated a nano particle coated tapered plastic optical fiber (POF) for sensing ammonia gas. Here we prepared nano particle from leaf extract and characterized it by UV and PL diffraction spectroscopy and the function ability of the fabricated sensor is tested by calculating its limit of detection (LOD) and Sensitivity.
Keywords:
