Application

Dowex 1X4 chloride form is a strongly basic (type I) anion exchange resin for fine pharmaceuticals. Dowex 1X4 ion exchangers have been used to remove iodinated contrast media (ICM), water pollutants, from the water phase, suggesting a removal method for use in aquatic environments. Dowex 1X4 has also been used to determine partitioning of heavy metals (Ca, Mg, Fe and Zn) in cow milk.
Strongly basic (type I) anion exchange resin for fine pharmaceuticals; meets requirements of FDA Food Additive Regulation 21 CFR 173.25.

An operationally defined fractionation protocol was developed to study the partitioning of Ca, Mg, Fe and Zn in UHT cow milks. The method was based on sorption of distinct metal species by two ion exchange columns, namely strong cation exchanger

Iodinated contrast media (ICM) are persistent and ubiquitous water pollutants. Because of their high water solubility and biochemical stability, their phase-separation and recovery from the aquatic environment is very difficult. Here, borate was chosen as a complexing agent of the

Questions

1–2 of 2 Questions  

  1. How can a Dowex type 1 resin in the chloride form be converted to the carbonate form?

    1 answer

    1. As one might expect, the procedure requires the use of sodium carbonate (Na2CO3).Citation: Journal of Experimental Medicine, 120, 1007-1018 (1965).From page 1011 of that paper:"A 2 mL column of washed Dowex-1X8 200 to 400 mesh, in the chloride form, was converted to the carbonate form by washing with 1 M Na2CO3 until no chloride could be detected in the eluate. It was then washed with distilled water until the pH of the eluate reached neutrality". The simplest test for chloride is to use a dilute silver nitrate solution. If mixing a few drops of the eluate with a few drops of a silver nitrate solution results in a silver chloride precipitate forming, that would an indication that the eluate contains chloride. You could also use a chloride-specific electrode, if you have access to one.
