1 | The spectral-luminescent properties of humic acids, humic triplet excited states, its influence on organic ecotoxicants, using the luminescence biotests for study of detoxification the aqueous solution in the presence of humic acids are discussed Keywords: Humic acids, spectral characteristic, irradiation | 1186 | ||||
2 | In this paper there were presented the results of study effect of irradiation on antioxidant activity of humic acids from Vasugan bog’s hight-moor peat by chemiluminescence method. It was showed the antiradical activity of humic acids. The antiradical activity increased after UV-irradiation. The sun irradiation was feebly influenced on antiradical activity of humic acids. Keywords: humic acids, antiradical activity, antioxidant activity, chemiluminescence, sun irradiation, UVirradiatioin | 833 | ||||
3 | The contents of carbon in mire waters changes from 53 before 92.5 mg/l with extreme parameters 27.8–145 mg/l. Mathematical model of carrying out materials is designed for surfaces of watershed basin. The calculations show that long-time average carrying out of carbon with watershed basin at different years forms 4.3–12.8 g/(m2 year), including carbon in humic and fulvic forms, carrying out of which reaches vegetation period 98 % from the general of carbon carrying out at certain months. Keywords: carbon, peat moss bogs, geomorphological profile, carrying out, humic material, chemical composition, mire water, balance, stand; bear, modeling | 810 |
