My research is concentrated on Pulsed Corona Discharge (PCD) technology and its implementation for water treatment and modification of various products. The method has hydroxyl-radical and ozone as the main oxidants species effective in oxidation of organic molecules. Lignin modification for its utilization in valuable products by oxidation at maximum cost efficiency, and study of PCD in pharmaceutical compounds abatement in water bodies are the main lines of research at that moment. PCD proved itself as competitive water treatment method surpassing the closest competitor such as ozonation. Such antibiotics as amoxicillin, doxycycline, sulfametizol as well as meglumine acridоnacetate are easily oxidized by PCD with relatively small energy consumption.

Lignin is one of the most abundant natural polymers and it is a potential raw material for various products including phenolic substances and aromatic aldehydes (vanillin, syringaldehyde, vanilic acid, syringic acid). My study considers the hypothesis that modification of lignin with PCD oxidation at ambient conditions may appear feasible and beneficial method of lignin modification by its economic performance and environmental safety. The positive tendency in aldehydes formation was observed during PCD treatment.

The degradation of others compounds, such as phenol, humic acids, ibuprofen, paracetamol, β-estradiol were also studied
