RESIN FOR ADSORBING BORIC ACID AND METHOD FOR REDUCING BORATE ION IN BORIC ACID-CONTAINING WATER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for industrially and advantageously reducing borate ions in boric acid-containing water.;SOLUTION: This resin for adsorbing boric acid is a spherical particle having a functional group with an affinity for the borate ions and bound to a substrate composed of a cross-linked polystyrene or a cross-linked polymethacrylic ester and has 100-450 μm volume-average particle diameter of the particle and ≥50% volume abundance ratio within the average particle diameter ±10%.;COPYRIGHT: (C)2002,JPO
