AmberSep IRA743 Chelating Resin is a unique ion exchange resin specifically designed and used to remove boric acid and borate from water, magnesium brine, or other solutions under a variety of conditions.
The presence of boron compounds, even in very small concentration, is frequently a concern in drinking and irrigation water, in ultrapure water (as used in the semiconductor industry), and in other chemical processes.
Boric acid can be removed from water with conventional ion exchange resins, but the exchange is not selective and, therefore, impractical. The selectivity of AmberSep IRA743 for boric acid is high, even in saline backgrounds.
The high selectivity of AmberSep IRA743 for boric acid is due to a unique, sugar-like active group. The borate ion makes a very stable complex with the glucamine group, while other anions do not react at all.
