Abstract:

The process of interaction of halogen-containing organic compounds (Freons: 134a, 22, and 12) with calcium carbonate surface under illumination and conditions close to the tropospheric ones was studied. It is suggested that the interaction is a destructive photosorption of Freons (134a or 22). This interaction yields the surface calcium fluoride and calcium chloride. The spectral dependence of the effective quantum yield for Freon 134a is determined.
