Description
AB - 17 - 8 ANION EXCHANGER
Anion exchangers - the synthetic anion - exchange polymeric materials representing the firm polymeric bases containing ionizable group of the main character in macromolecules. On the basis of basicity factor anion exchangers divide into three groups: weak - basic, strong - basic and sredneosnovny. The weak - basic anion exchangers containing in quality of ionizable group primary ( - NH2), secondary (> NH) and tertiary (≡N) amino groups, exchange mobile anions only in acidic environment. Anion exchangers - high - molecular polyamines can be as in hydroxylic, and salt form.
GOST 20301 - 74
