The kinetic models of aerosols interactions with main trace components (MTC) of Antarctic atmosphere concidering the influences of chemical, mineralogical and phase composition of MTC and external factors. Ideas of heterogeneous chemistry Antarctic atmosphere were developed, as well as stochastic models of adsorption equilibrium, of chemisorption kinetic, of desorption, of MTC bimolecular reactions on inhomogeneous surface particles, methods of reverse analyses for these problems and the influence of aerosol composition and MTC structure of molecules on the thermodynamic of adsorption equilibrium, kinetic of desorption and chemisorption with their participation. Structural parameters and energetic heterogeneity of solid particles surface were studied using quasi-equilibrium deryvatohrafiyi, non-isothermal desorption of contaminants, inverse gas chromatography and kinetic flyuorometry. Stationary kinetic of aerosol's heterogeneous remove from the atmosphere were analysed considering influences of such parameters as heterogeneity of solid particles surfaces, their morphology, phase and chemical composition, particles size, etc. Developed models and approaches can help to improve modern climatic and atmospheric models and multiphase Antarctic mass balance models that describe transport of contaminants in the Antarctic environment.5481
