Abstract:

The adsorption and photosorption properties of aerosol micro particles produced by grinding (dispersion) of mineral brucite crystal, Mg(OH)₂, under ambient air were investigated. The composition analysis of adsorption layer of micro particles formed by grinding of crystal is carried out. The kinetics of photodesorption of molecules from micro particle surfaces and the interaction of Freon 22 (CHF₂Cl) with its surfaces under darkness and illumination conditions were studied. The quantum yields and its spectral dependencies of CO₂ photodesorption and CO photoadsorption were determined.
