WEAK-BASED ANION-EXCHANGE POLYMERS

By polymerization of melamine and furfural in the presence of diphenylamine there was obtained new weakly basic anion exchanger. There was investigated the basic physicochemical properties of anion exchanger. With the use of potentiometric titration, it was found that sorption by сopper ions is depending on the pH with the form of complexes or sedimentation.
