HUMIN REMOVING AGENT AND REMOVING METHOD OF HUMIN CONTAINED IN WATER

摘要

PROBLEM TO BE SOLVED: To provide an effective removing method of humin and a polymer used therefor.;SOLUTION: A cationic polymer having a cationic monomer formed by bonding a hydrophobic group to a cationic group as a main component, or a cationic polymer which is a copolymer having a cationic monomer and a hydrophobic monomer with a solubility parameter of 7.8-10.5 (cal/cm)^1/2 as a main component, is added to water containing humin to form a compound of humin and cationic polymer. By removing the compound, humin can be removed.;COPYRIGHT: (C)2009,JPO&INPIT
