| 1 | The influence of mechanochemical activation of peats on the change of structure of humic acids and their acid properties has been studied. It was shown that the yield of humic acids increases in 6–7 times, their molecular weight decreases and the quantity of acid functional groups increases in their structure under mechanochemical treatment of peats Keywords: Peat, Mehanochemical extraction, humic acids, mineral component | 1821 | ||||
| 2 | The influence of mechanical grinding in abrading and cutting mills on the structure of peats, their physical, chemical and structurally-mechanical properties has been investigated. It was shown, that lowland peat has a big stock of elements of a mineral food, than high-moor peat. The grinding of high-moor peat increases its bulk density and leads to insignificant increase in a moisture capacity of both types of peat. Besides, the change of sizes of peat particles, group composition and rheological properties of peats has been investigated. Keywords: peat, grinding, mills, composition, properties | 1482 | ||||
| 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.
