Iron dispersant for boiler water |
| abstract |
A composition and method for effectively dispersing iron in water to prevent iron oxide deposits is disclosed. The composition includes a first component which is an acrylic copolymer having repeating units mixed with a second component which is either a homopolymer or copolymer of an acrylate or a methacrylate. The first component includes an acrylic or methacrylic hydrazide and its repeating units include an acrylic or methacrylic amide or alkyl ester. Iron containing water may be treated by adding 0.01-10 mg composition to each liter of water. |
