Description

Application

Strongly basic (type I) anion exchange resin specifically suited for demineralization of high organic waters, removal of organic material and color bodies, with low silica leakage. This resin meets requirements of FDA Food Additive Regulation 21 CFR 173.25.

Dowex® 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. Dowex® anion exchange resin has high uranium sorption and can be used to determine groundwater and uranium contaminant fluxes and uranium ratios in soil samples.

Other Notes

The Dowex® Marathon® 11 is a superior resin to the Dowex 11. The Dowex Marathon series provides narrower particle distribution, better efficiency, and improved kinetics when compared to the gaussian Dowex products.
