The passage of the electrical current (the voltage 1-2 kV) through dielectric tubes filled with electrolyte solutions causes the formation of luminous plasma zones moving along the tube. The visual observations and camera control (24 frames/s) show the possibility of the simultaneous existence up to three luminous zones. They may be as cylinder with the length up to four diameters of the tube, disc or ring. The estimations result in the lifetime of these luminous objects ≤ 0.2 s. The discharge current oscillography demonstrates the sequences of the attenuated pulses modulated with the frequency of 50 Hz. This type of plasma-solution system demonstrates high efficiency modification of the polymer materials.

The effect of atmospheric-pressure gliding discharge action on an electrolyte solution was studied. The hydrogen peroxide yields in the solutions were defined after the discharge treatment, as well as the pH and elecrtoconductivity values. Gliding discharge was shown to be more effective than glow discharge for H 2 O 2 formation in the electrolyte solution.
