Adsorption or desalinization

摘要: PURPOSE:To provide an adsorption or a desalination method which can deal with large amount of liquid and elutes few impurities from resin by adsorbing separating electrolytic substances introducing into specified anion exchange solely mixed bed it styrene-based strongly acidic cation resin. CONSTITUTION:There is prepared crosslinked polymer consists 30-99.5mole% repeating monomer units represented the formula I, II, 0.1-60mole% unit III, 0-60mole% another copolymerizable defined any formulae III. Depending on case that functional group having highest mole percentage among groups primary amino group, binary tertiary quaternary introduced either exchanger regin have different weakly-basic-group capacities neutral salt decomposition thus are adsorbed separated.
