Abstract:
     The present invention relates to a resin for removal of perchlorate, methods for manufacturing the resin, and methods and systems using the resin. The resin has a high selectivity coefficient. Given the performance properties of the resin, an economical method of servicing a water treatment system is also provided. The method includes loading into and/or unloading from the water treatment system a perchlorate removal resin having the high selectivity coefficient. In one aspect, the perchlorate removal resin has quaternary alkylamine functionality. In another variant, the resin is capable of removing at least two times the amount of perchlorate per cubic meter of the resin than a conventional perchlorate removal resin. This provides substantial commercial benefits to users.
