Obtaining nano-sized silver particles in aqueous solution under the influence of the contact nonequilibrium low-temperature plasma

В данной работе исследовалось влияние процесса плазмохимической обработки водных растворов, содержащих ионы серебра, на образование наноразмерных частиц серебра, их размеры и характер их изменения в заданном временном промежутке. Даны рекомендации к повышению устойчивости частиц путем введения стабилизирующих добавок. Полученные результаты планируется использовать для создания уточненной математической модели процесса плазмохимической обработки жидких сред.The influence of plasma-treating aqueous solution containing silver ions for formation of the nanoparticles of silver, their size and their variation over a predetermined time interval. As a processing tool to use contact nonequilibrium low-temperature plasma is formed between the electrode (anode), located in the gas phase and the liquid surface and recessed electrode in there. The electrolytic solution AgNO3 in the distilled water used as cathode. Studied the characteristics of the obtained nanoparticles, their absorption spectra, size, stability in aqueous medium and in the dry state in powder form. Recommendations to improve the stability of the particles by the introduction of stabilizers. The results will be used to create a mathematical model of plasma-chemical treatment of liquid media
