The composition of surface compounds desorbing in darkness and under irradiation from microparticles of precipitated aerosol Ca(OH)2 without calcium carbonate were investigated. The quantum yield quantities and its spectral dependencies for the photodesorption from aerosol microparticles and the oxygen photoadsoption were determined.
