This paper presents the results of investigation of the plasma-liquid system with the secondary discharge supported by atmospheric pressure microdischarge in the vortex Ar flow. The plasma treated fluids were aqueous solutions of AgNO<sub>3</sub>. The microplasma discharge was powered by a DC supply. The plasma channel behaviour was characterized by photo/video recording, also plasma was studied using emission spectroscopy technique. The working liquid and firm products created after the treatment were studied also.
A microdischarge system has been studied with the use of various plasma gases. The results of emission spectroscopy and measurements of the current-voltage characteristics are reported. The discharge parameters for the vibrational and rotational levels of plasma components are determined. K e y w o r d s: microdischarge, vortex flow, optical emission spectroscopy.
The paper is devoted to study of the plasma-activated synthesis of organic compounds with optically activity. Synthesis was carried out in plasma-liquid system with a rotating gliding discharge submerged in a liquid. The initial reagents of synthesis were ethanol, ammonia, and CO<sub>2</sub>. The possibility of the influence of the electric field direction on the optical activity of the products of plasma-activated synthesis is shown.
