Production of surface agents for limiting the growth of bacteria and fung based on silver nano and microparticles made by electrochemical methods on an industrial scale

The article presents the basics of a new technology for the production of surface agents for limiting the growth of bacteria and fungi based on silver nano and microparticles made by electrochemical methods on an industrial scale, developed on the basis of the results of industrial research and development works. There is a growing interest in the use of nano and micromaterials in various fields of the economy, including cosmetology, arable and livestock agriculture, and medicine. Silver is a biologically active element that strongly limits the growth of bacteria, fungi and even viruses. In the case of water colloids produced by electrochemical methods on an industrial scale, the processes accompanying the reactions are not controlled with an appropriate level of accuracy. The authors developed methods to automatically control these processes for the first time based on the optical properties of water colloids. As a result of the project, theoretical foundations for control systems as well as functional diagrams along with appropriate program codes were developed. The technology was tested in the production line of water molecular silver colloids used in cosmetics such as creams, mists, cosmetic waters and serums. Thanks to it, the stability of the reaction and the quality of the manufactured intermediates were increased. The technology will also be applicable to silver colloids intended for agriculture and other industries.
