Specialty Ion Exchange Resin for Boron Removal/Separation

PRODUCT DATA SHEET:

KP7523 is a macroporous styrene series weak-base ion exchange resin synthesized with special technology, targeting removal of borate radicals. Coordinated with its peculiar chelating amine functional group that is featured to form a very stable complex with boric acid anions within neutral or alkaline solutions, this special resin is commonly applicable to separation and removal of boron within boron-containing aqueous solutions such as drinking water and irrigation water.

For its integrated particles and highly firm structure, KP7523 performs efficiently in its anti-osmotic, regeneration and flushing effect. Thereby it avails widely in the treatment of boron-contaminated ground water for safe irrigation, or green-discharge control against boron poisoning when it comes to the violated discharge of untreated or improperly treated boron-containing wastewater or industrial sewage.
