Acid-base properties of fibrous polyampholytes with aminodiacetic functional groups
Polyampholytes, containing aminodiacetic functional groups, on the base of polyacrylonitrile fiber Nitron C were obtained by the amination reaction of nitrile groups with polyamines (number of repeating units from 1 to 5) and subsequent alkylation with monochloroacetic acid. The experimental results of potentiometric titration and sorption of supporting electrolyte (kCl) ions by synthesized ion exchangers were obtained, which made it possible to determine the acidity parameters of functional groups: the presence of four types of cation exchange and two types of anion exchange groups was detected in polyampholytes, the sequence of their neutralization in the titration process was established.
