FIELD: chemistry.
SUBSTANCE: invention relates to a method of reducing erosion and/or corrosion resulting from an impact of aggressive waters in industrial systems, namely for reduction of loss of copper ions from water systems, containing a copper-containing surface, which is in contact with water of the said water system. The composition contains a synergic combination of at least two different benzotriazoles or their salts, and the said synergic composition provides a corrosion-resistant barrier on the copper-containing surface.
EFFECT: composition ensures inhibition of corrosion by formation of a protective film, resistant to halogens in aggressive waters with high content of solid particles.
