摘要：

Temperature-programmed desorption mass spectrometry (TPD MS) is discussed with reference to studies of modified pyrogenic oxides. Simple theoretical models are presented in order to allow an approximate analytical treatment of TPD MS data. The formulae for rate constant are presented for first-, second- and third-order reactions. Products of thermal decomposition of carbonized surface layer are observed and identified. The different pathways of uni- and bimolecular desorption were investigated by temperature-programmed desorption mass spectrometry. The rate constants of reactions were derived from TPD MS measurements. Applications of TPD MS to investigation of endocrine disruptors fate and formations on the solid aerosol surface are discussed.
