What is dowex 50 used for?
Dowex 50WX8 (HCR-W) hydrogen form is used: As stripper resin and can be regenerated by 0.25N sulphuric acid when exhausted. As a catalyst. In deionizing supernatant fraction samples for paper chromatography.
Is dowex a solvent?
DOWEX resin desiccants are reacti- vated by drying at relatively low tem- peratures (150°C; 300°F). As such, they exhibit a significant advantage over other desiccant materials, such as silica gel and molecular sieves. For more information see “DOWEX Resins as Organic Solvent Desiccants”.
How does dowex resin work?
Put simply, ion exchange is a reversible interchange of charged particles—or ions—with those of like charge. This occurs when ions present on an insoluble IX resin matrix effectively swap places with ions of a similar charge that are present in a surrounding solution.
What is Dowex ion exchange resin?
DOW Ion exchange (IX) resins are polymers that are capable of exchanging ions with ions in a solution that is passed through them. DOW’s world-class IX resins serve applications as diverse as industrial water softening, pharmaceutical formulations, sweetener purification, mining and more.
How do I use dowex 50WX8?
Conventional sample clean-up procedure with Dowex 50WX8
- Set 6 mL bond elution reservoir in vacuum filtration unit.
- Fit reservoir with frit at the bottom.
- Fill up the reservoir with homogenised wet Dowex 50WX8 corresponding to 1.75 g wet resin material.
- Cover resin with frit.
- Rinse CER bed with 20 mL UPW (step 1)
Is dowex resin an acid catalyst?
DOWEX ion exchange resins may be used as acid catalysts at tempera- tures as high as 120°C, beyond which resin degradation occurs.
