The adsorption behavior of free acid on D354 macroporous weakly basic anion exchange was fallowed by electric conductance technique.
The strongly basic, weakly basic and non-basic nitrogen contents and acid values of the residues and their fractions were determined with non-aqueous potentiometric titrations and elementary analysis.
The operation regularity and characteristics of D354—FC weakly basic anion exchanger used in water treatment are presented.
