DuPont™ AmberLite™ XAD™ polymeric adsorbent resins are nonionic, macroporous crosslinked resins that selectively adsorb molecules based on a combination of hydrophobic interactions and molecular size. These resins can be used in single-use adsorption mode to capture impurities from products streams...

The strategy employed in this study was based on the adsorption of the ion-associate complex, formed between the cationic PQT2+ and the dodecylsulfate anion, which presents high affinity by the hydrophobic resins. The effect of several parameters that could affect the efficiency of adsorption (...
AMBERLITE(R) XAD-1180 was used in rapid fractionation technique, and it was used as sorbent for HPLC analysis. Uses Hydrophobic compounds up to 40,000 MW; antibiotics; pharmaceutical manufacturing; surfactants; bitters; separation of large organic molecules (especially proteins). More efficient than...
tensive, because of their hydrophobic nature and their The commonly used methods to carry out removal high specific area. Nowadays, these porous organic resins of traces of organic compounds from aqueous streams have replaced activated carbon for the isolation of or- of PUREX process are; diluent ...
Since the hydrophobic alkyl chains of D2EHPA physically entangle with the surface polymer chains of Amberlite XAD-4, the immobilized extractant has good stability on the resin surface. This D2EHPA-modified Amberlite XAD-4 can be used for the separation of lead and copper ions as an ion-...
FTIR shows that the immobilization of the extractants results from hydrophobic interaction between the alkyl group of the extractants and the aliphatic chain of the support, and also from other mechanisms, like polar or electrostatic forces. Batch adsorption experiments for the removal...
On the other hand, the sorption coefficient for XAD-2 was two orders of magnitude lower than that for XAD-7HP. PFC sorption on XAD-7HP increased with an increase of the perfluorocarbon chain length of PFC and a decrease of the solution pH, indicating the importance of hydrophobic and ...
