Taking into consideration the fact that discharge formation and discharge regimes are a complex multi-stage processes influenced by many different factors, to achieve the goal of the project, it is necessary to develop the experimental stands to study the individual factors. In particular, the influence of the bias voltage on the dynamics of the bulk charge in the discharge gap will be studied. The optimal power supply parameters for stable and long-term plasma generation and ozone synthesis will be determined. Another direction is the latest highly-efficient technology for extracting heavy metal ions from water solutions, namely, the capacitive deionization technology (CDI), which is sometimes called electrosorption desalination. Due to the CDI technology, which is an alternative to reverse osmosis, dissolved ions can be effectively removed from water. Nitrates and heavy metals can also be removed and water hardness can be reduced. The optimal regimes for sorption/desorption of heavy metal ions depending on the valence of ions, temperature and pH of water solution will be determined. popup.description2 The object of the study – plasma-chemical reactors with a pulsed negative corona in oxygen with combined power supply in an electrode system with a rotating cathode. The purpose of the work – to determine the conditions for achieving an increase in the maximum amplitude of the high-voltage pulse, when exceeded, the negative corona turns into a spark. The main scientific results are as follows: 1. For the first time, the existence of a threshold cathode motion speed has been experimentally shown, exceeding which leads to an increase in the maximum amplitude of high-voltage pulses, discharge current and the amount of synthesized ozone. 2. For the first time, the dependence of the electrodynamic characteristics of the negative corona in oxygen and its ability to synthesize ozone on the speed of cathode motion has been shown. The location of the negative ion cluster in the discharge gap and its transverse size have been estimated. 3. It is shown that the magnitude of the cathode movement speed relative to the anode does not affect the formation and development of the current pulse, but increases the maximum possible amplitude of the high-voltage pulse, before the transition of the negative corona into a spark discharge.
