CORROSION OF CARBOT STEELS IN DISINFECTANT SOLUTIONS

Abstract
Disinfection of various surfaces is used everywhere in different areas of human activity. Disinfection of surfaces has gained particular relevance in recent years. However, in the process of disinfection, solutions with high concentrations of active substances are used. The most common substances used for disinfection are those containing chlorine. Among them, sodium hypochlorites, calcium hypochlorites, and bleach are most commonly used. In the process of surface dis-infection, the materials of the treated surfaces are destroyed. This can lead not only to the migration of leached-out metals but also to the destruction of materials and structures. As an alternative disinfectant, the article considers ozone solutions in water. Ozone has found widespread use for water disinfection, but it has not found wide application for surface disinfec-tion. The article investigated the corrosive effect of disinfectants on carbon steels St3 and 08. For research, chlorine-containing solutions were used at a concentration of 2 wt.% in terms of hypochlorite ion and ozone-saturated water as an alternative disinfectant solution. The research results showed that chlorine-containing solutions have the greatest corrosive effect on the studied stainless steels, among which the sodium hypochlorite solution has the greatest corrosive effect. The use of ozone-saturated water is characterized by the lowest values of corrosion currents.
