ResinTech SIR-150 is a borate selective macroporous chelating weak base anion resin. Its unique functionality provides exceedingly high selectivity for boron in almost any aqueous solution, yet can be regenerated with acid and then neutralized with various alkaline salts prior to use. SIR-150 is intended for all borate removal applications including potable water, ultrapure water, and boron removal from concentrated brines.
