Chemical characterization of iron in atmospheric aerosols
Abstract The total Fe content, the soluble fractions of Fe(II) and Fe(III), and several species of Fe were determined in various atmospheric aerosol samples by means of atomic absorption spectrometry, ion chromatography and Mossbauer spectrometry.
CHARACTERIZATION OF IRON COMPOUNDS FROM URBAN AND RURAL AEROSOL SOURCES
Abstract Iron plays an important role in the chemistry and physics (by varying the hygroscopicity) of the atmosphere. Bulk samples were taken from an air-conditioning device, from the electrofilter of a gas–oil power station of the Technical University of and from rural sites near Darmstadt, situated between medium-altitude mountains and with a climate dominated by air masses from the west. Samples were collected in urban and rural (meadow) air, from different waste incineration power stations, from the exhausts of a gasoline and from a diesel motor car, and from a private gas fired heating system. The samples were characterized for elemental composition by total reflection X-ray fluorescen…
