Bordun I. Scientific and methodical bases of environmentally safe technologies of water treatment with the use of physical and chemical methods

The thesis is devoted to the decision of an actual scientific and applied problem in the field of ecological safety – development of environmentally safe technologies of water treatment with the use of physical and chemical methods for maintenance of rational use of water resources, utilization of wastes of agriculture and the food industry and reducing the release of harmful substances into the environment. The efficiency of new methods of disinfection in sugar production on the basis of electrochemically activated solutions of sodium chloride is theoretically substantiated and experimentally proved, which allowed to increase the level of ecological safety of such production. The electronic and fractal structure of nanoporous biocarbon synthesized from corn stalks and beet pulp were studied. The suitability for ultrasonic modification of such biocarbon has been established, which makes it possible to significantly increase its functional hybridization and sorption capacity with respect to water pollution. A new type of sorbent, a modified biocarbon with magnetic properties, was synthesized from plant waste and successfully tested. The obtained sorbent has a high adsorption capacity against pollutants in combination with the convenience of its separation from aqueous solutions, which makes it possible to use it for purification of aquatic environments and increase the environmental safety of the hydrosphere. Theoretical bases of monitoring the effect of nanoparticles dispersed in the aquatic environment on living organisms have been established.
