| 21. | The chemicals, called ion exchange resins, are used by the petroleum, sugar and pharmaceutical industries, among others.
|
| 22. | Ion-exchange resins are also used as excipients in pharmaceutical formulations such as tablets, capsules, gums, and suspensions.
|
| 23. | The salt is used to recharge an ion-exchange resin which itself is used to soften the water.
|
| 24. | The company buys styrene to make ion-exchange resins, which are used to purify water and other liquids.
|
| 25. | Urine from victims was treated with ion exchange resin to compact the waste for ease of storage.
|
| 26. | Although 90 % of the dissolved tungsten is technically recoverable by ion exchange resins, recovery is uneconomic.
|
| 27. | There are some ion-exchange resins that do remove organic ions, such as MIEX ( magnetic ion-exchange ) resins.
|
| 28. | For example, smaller particles such as clay tend to tightly bind to chemicals, acting like ion exchange resins.
|
| 29. | The ion exchange resins act to retain the ions, allowing these to be transported across the ion exchange membranes.
|
| 30. | Like water softeners, dealkalizers contain ion exchange resins that are regenerated with a concentrated salt ( brine ) solution-NaCl.
