Abstract

Abstract
In the present work a comparative analysis of the determination of NO2 in the atmosphere using IC and spectrophotometry was carried out. A sampling of the pollutant using passive sensors in an urban environment and industrial city of Medellin was made. In a first stage, samplings of 1 to 3 months were realized, while in a second phase sampling of 2, 5 and 7 days were made. In addition, two types of substances used in the analysis by IC for the extraction of NO2 were studied. It was found that the IC technique has a detection limit lower than the spectrophotometry technique. The chemistry of NO2, the techniques used for quantification, advantages and disadvantages of using passive samplers and exposure and storage times are included in the literature review.
