Abstract
Oxidation of I- and S2- anions on the silica gel surface by atmospheric oxy gen was studied at room temperature. The possibility and rate of oxidation processes are determined by the content of silica gel and oxygen in the sys tems. Tentative interpretation of the results is based on the assumption th at a highly reactive singlet O-1(2) species is formed in the oxygen ensembl e on the silica surface.
