ANION EXCHANGE RESIN FOR PRODUCING ULTRAPURE WATER AND PRODUCTION OF ULTRAPURE WATER USING THE SAME

摘要

PURPOSE: To provide a strong basic anion exchange resin for producing ultrapure water especially effectively removing fine particles in treated water and reducing the load of a succeeding membrane device. ;CONSTITUTION: The objective strong basic anion exchange resin is based on a crosslinked copolymer of a monovinyl aromatic compound and a polyvinyl aromatic compound and is characterized by that the half width (¹³C-nuclear magnetic resonance absorptiometery) of the absorption spectrum of carbon of the alkyl or alkanol group of the quaternary ammonium group thereof is 7.5ppm or less.;COPYRIGHT: (C)1993,JPO&Japio
