On-Line and In-Situ Identification of Air Pollution
The elemental, iron-phase, and oxidation state analysis of urban aerosol samples, collected from different sites in Vitória metropolitan region, ES, Brazil, was carried out using Mössbauer (MB) Spectroscopy (MBS) and X-ray fluorescence (XRF) techniques. A portable XRF spectrometer for elemental analysis from Na to Fe, and the miniaturized MB spectrometer MIMOS-II have been installed together using a 100 mCi 57 Co(Rh) MB source for XRF excitation. Both measurements can be performed simultaneously. For continuous and fast characterization purposes a software package was developed for Mössbauer and XRF analysis. The software is based on genetic algorithm, fuzzy logic and artificial neural networks.
