一般描述

"p.a." grade resins have been cleaned to remove residual metals, and are purified for analytical use.
Dowex 1X8 is a strongly basic anion exchange resin which is used as an absorbent in solid phase extraction.

应用

Dowex 1X8 chloride form was used:
  • to separate the 3H2O from D[2-3H] glucose using Dowex columns
  • in a assay to determine the pantothenate kinase using Dowex column
  • to separate inositol phosphates (IPs) from myo-[3H]inositol by Dowex chromatography
用于精细化工的强碱性(I 型)阴离子交换树脂;满足 FDA 食品添加剂法规 21 CFR 173.25 的要求。

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

    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.
