Description
General description
Amberlite XAD-2, a hydrophobic copolymer of styrene-divinylbenzene resin, requires longer purification process and is used as a sorbent. Amberlite XAD-2 resin depending upon the aromaticity and size of the hydrophobic groups sorbs organic compounds through low-energy physical interactions.[1]
Nonionic macroreticular resin that adsorbs and releases ionic species through hydrophobic and polar interactions; usually used under isocratic conditions.
Specifications:
Application
Amberlite® XAD®-2 was used:
• as adsorbent in the extraction of organochlorine compounds using Soxhlat extraction technique[1]
• as adsorbent in the extraction of honey samples using column chromatography for HPLC analysis[2]
• in adsorption chromatography[3]
Polyaromatic adsorbent resin for hydrophobic compounds up to MW 20,000: phenols, organic removal, surfactants, aroma compounds, antibiotic recovery. May be used as support for catalyst or metals removal. For cleaned US EPA versions, see Supelpak-2 and Supelpak-2B.
