Swelling resin ion exchange Determination
1 Scope
This standard specifies the determination of the ion exchange resin from an ion patterns becomes another ion patterns change in volume method.
This standard applies to all types of ion exchange resins Swelling was measured. For more weak type resin containing groups, according to weak-Tree
Fat was measured.

3 Method Summary
Repeatedly treated with acid solution to eliminate resin irreversible after expansion, it will turn into a single ionic resin. Strong resin washed with pure water tree
Lipid particles of the external acid or base. Salt form weak acid type resin was washed with corresponding low concentration of alkali solution, so that they end up in (0.005 ~
0.01) mol/acid, alkali solution L, the volume of the resin was measured irregularly arranged in a graduated cylinder, according to the resin in different ionic under volume
Swelling count.
4 instruments and equipment
4.1 Glass-exchange column. with GB/T 5760.
4.2 funnel. with GB/T 5760.
4.3 cylinder. 50.0mL.
5 Reagents and solutions
5.1 hydrochloric acid solution [Ba (HCl) = (1.00 ± 0.01) mol/L]. pure chemical formulation.
5.2 solution of sodium hydroxide [Ba (NaOH) = (1.00 ± 0.01) mol/L]. pure chemical formulation.
Hydrochloric acid solution was washed with 5.3 [Ba (HCl) = (0.005-0.01) mol/L]. pure chemical formulation.
5.4 sodium hydroxide washing solution [Ba (NaOH) = (0.005-0.01) mol/L]. pure chemical formulation.
5.5 Reagent water. Reagent meet three water GB/T 6682 regulations.
6 Sample preparation
6.1 Sampling by GB/T 5475 carried out.
6.2 Pretreatment of the sample according to GB/T 5476 carried out.
6.3 taking about 25mL sample into a glass column exchange within the sample layer should be no air bubbles (if any air bubbles out of the agitation with a glass rod). Sample layer
The retention level (4 ~ 5) cm.
