Metal corrosion prevention methods for water systems

Abstract

The invention relates to a method for treating metals for use in water systems that can minimize or eliminate the use of phosphorus compounds or metal salt compounds that act as burdens on the aquatic environment, such as eutrophication or toxicity in water, and which can be applied over a wide range of water quality. The invention relates to a method for treating metals for use in water systems. which utilizes copolymers consisting of (met)acrylic acid monomers and sulfonic acid-containing monomers, and organic acid compounds with an organic acid corrosion resistance index greater than or equal to 4.
