摘要： This invention is directed to a method for controlling the formation of silica/silicate deposits in aqueous systems by adding an effective amount, preferably at least 0.1 ppm, of a designated phosphonate and, optionally, a carboxylic/sulfonic polymer or salt thereof to the aqueous system being treated. Borate or molybdate ion sources may also be added.

摘要： A method for controlling the formation of silica/silicate deposits in aqueous systems by adding an effective amount, preferably at least 0.1 ppm, of 2-phosphonobutane tricarboxylic acid-1,2,4 and, optionally, an anionic polymer, preferably a carboxylic/sulfonic polymer, or salts thereof to the aqueous system being treated. Borate or molybdate ion sources may also be added.
