Field testing of samples containing hexavalent chromium and organic compounds were carried out, which showed the possibility of intensifying the processes of their heat treatment using solar energy. The correlation analysis between various factors of atmospheric exposure and changes in the state of sam-ples was performed. In the course of the study, an estimate was obtained for the wavelength ranges of the near-UV, visible and near-IR spectrum, within which photo-chemical reactions of hexavalent chromium re-duction are possible. The temperature and hydrostatic pressure influence on the chemical reactions intensity in the sample was also assessed. Based on the data obtained, theoretical pre-conditions of energy efficiency of heat treatment process were formed, which should be verified by subsequent laboratory tests.
