Application

AmberLite™ HPR4811 Cl Anion Exchange Resin Marathon 11 chloride form is a strongly basic (type I) anion exchange resin specifically suited for demineralization of high organic waters and removal of organic material and color bodies. AmberLite™ HPR4811 Cl Anion Exchange Resin anion exchange resin has high uranium sorption and can be used to determine groundwater and uranium contaminant fluxes and uranium ratios in soil samples.
Específicamente adecuado para la desmineralización de aguas con elevado contenido de compuestos orgánicos y cuerpos coloreados; bajo escape de sílice; cumple los requisitos de la Normativa 21 CFR 173.25 de la FDA sobre aditivos para alimentación.

Other Notes

Versión actualizada del Dowex 11, que ya no está en el catálogo del fabricante.
The Amberlite™ Marathon® 11 is a superior resin to the Dowex 11. The Amberlite Marathon series provides narrower particle distribution, better efficiency, and improved kinetics when compared to the gaussian Dowex products.

Synthetic resins are shown to be effective in removing uranium from contaminated groundwater. Batch and field column tests showed that strong-base anion-exchange resins were more effective in removing uranium from both near-neutral-pH (6.5)- and high-pH (8)-low-nitrate-containing groundwaters, than metal-chelating resins

The vertical distribution of the (236)U/(238)U isotopic ratio was investigated in soil samples from three different locations on La Palma (one of the seven Canary Islands, Spain). Additionally the (240)Pu/(239)Pu atomic ratio, as it is a well establish tool for
