Abstract
Maģistra darbā pētītas un analizētas smaku piesārņojuma koncentrācijas noteikšanas iespējas, izmantojot alvas oksīda elektroķīmiskos gāzu sensorus Figaro TGS: 2600; 2602; 2603; 2620. Darba izstrādes gaitā izstrādāts sensora kalibrācijas algoritms toluolam, benzolam un etanolam un novērtēta 4 dažādu sensoru spēja reaģēt dažādos piesārņotības līmeņa lauka apstākļos (mēslota un pūstošu kāpostu lauka, bijušās lopkautuves – esošā cūkkopības uzņēmuma tuvumā, Rīgas Brīvostas uzņēmumu apkārtnē un piena pārstrādes uzņēmuma notekūdeņu attīrīšanas iekārtu tuvumā). Darbā ir apzināts iepriekšminēto gāzu sensoru potenciāls un izvērtētas iespējas veikt vielu kvantitatīvu analīzi.
In master thesis pollution concentration determination options using tin oxide electrochemical gas sensors Figaro TGS: 2600; 2602; 2603; 2620 were studied and analyzed. During the research, theoretical sensor calibration algorithm for toluene, benzene and ethanol was developed and evaluation of sensor reaction to different levels of contamination outdoors (near to fertilized field, rotting cabbage field, the former slaughterhouse – now existing pig farm, in the vicinity of Freeport of Riga, dairy wastewater treatment plant) was carried out. Potential of use and possibilities to make quantitative analysis of contaminants in air were assessed.
