The influence of plasma chemical treating of aqueous solution containing silver ions for formation of the nanosilver particles, their size and their variation over a predetermined time interval are studied. As a processing tool is used the contact non-equilibrium low-temperature plasma that formed between the electrode (anode), located in the gas phase and the liquid surface, a recessed electrode therein. As the cathode it is used an electrolytic solution AgNO3 in the distilled water. Characteristics of the obtained nanoparticles, their absorption spectra, size, stability in aqueous medium and in the dry state in powder form are studied. The results will be used to create a refined mathematical model of plasma-chemical treatment of liquid media, the general equation of which is given in this article.
