1.1 These test methods cover the determination of the operating ion-exchange capacity of both powdered cation-exchange resins (hydrogen form) and powdered anion-exchange resins (hydroxide form). These test methods are intended for use in testing new powdered ion-exchange resins when used for the treatment of water. The following two test methods are included:
|
| Sections |
| Test Method A—Operating Capacity, Anion-Exchange | 7 to 15 |
| Test Method B—Operating Capacity, Cation-Exchange | 16 to 24 |
