What is Dowex 1X8 resin?
Dowex® 1X8 is a strongly basic anion exchange resin which is used as an absorbent in solid phase extraction. It is used in anion-exchange chromatography for separation.
What type of resin is Dowex 50?
fine mesh resin
What is the matrix for the Dowex® 50W X8 resin, Product 44504? The fine mesh resin is based on a microporous copolymer of styrene and divinylbenzene (DVB) (styrene-DVB gel).
What is the density of ion exchange resin?
560-960 g/l
In the water- swollen state, ion exchange resins typically show a specific gravity of 1.1-1.5. The bulk density as installed in a column includes a normal 35-40 percent voids volume for a spherical product. Bulk densities in the range of 560-960 g/l (35-60 lb/ft3) are typical for wet resinous products.
What is dowex resin?
Strong, insoluble structure—DOWEX fine mesh resins are based on a microporous copolymer of styrene and divinylbenzene (DVB) that results in maximum resistance to oxidation, reduction, mechanical wear and breakage. What’s more, this structure is also insoluble in common solvents.
What is dowex 50WX8?
General description. Dowex 50WX8 hydrogen form is used as stripper resin and can be regenerated by 0.25N sulphuric acid when exhausted. Dowex 50WX8 hydrogen form is used as catalyst. It is used in deionizing supernatant fraction samples for paper chromatography.
What is dowex used for?
In short, DOWEX UPCORE™ is an ion exchange system that can help your industrial facility increase the flow of demineralized water it is able to access while decreasing chemical use and providing a much higher-quality water for making steam than other more conventional technologies, all while decreasing the amount of …
How many times resin can be reused?
The results indicated that cation exchange resin can be reused for several times with good recovery efficiency. After 5 times reuse, the cation exchanger regenerated via 0.5N H2SO4 at 15min contact time achieved about 83.4% recovery efficiency for NH3-N from landfill leachate.
How do you calculate resin ion exchange capacity?
Total capacity is actually determined on a dry-resin basis as meq/dry gm and converted to wet values (meq/mL) based on moisture content of the resin. Tests are typically run with H+/Na+ exchange rather than Ca++/Na for cation. Ion exchange systems work by exchanging ions on a one-for-one equivalency basis.
