DuPont™ AmberLite™ XAD™ 7HP is a crosslinked aliphatic acrylic resin that combines high surface area with a mean pore diameter of 550 Å. Due to its aliphatic nature, it can adsorb non-polar compounds from aqueous systems and can also …

DuPont Adsorbent Resins provide advantages over silica based packings due to their physically and chemically stable polymeric structure. Ability to use aggressive mobile phases for selectivity optimization. Clean-in-place easily with strong acid or base.

The goal of this study was to obtain a new adsorbent material by functionalizing through impregnation a commercial polymeric support that was both inexpensive and environmentally friendly (Amberlite XAD7) with crown ether (di-benzo-18-crown-6—DB18C6).

Apr 28, 2023 · According to the obtained results, the (AXAD-7) resin impregnated with CYANEX-272 performed well in removing both Ce (ΙΙΙ) and La (ΙΙΙ) ions from aqueous solutions with well stability during...

Dec 3, 2024 · This book discusses the various inherent divisions of cyclodextrins (CDs) and XAD resin. Cyclodextrins are among the most remarkable macro-cyclic compounds, and Amberlite XAD-4 resin is a non-polar hydrophobic styrene-divinyl-benzene copolymer that takes the …

Oct 12, 2020 · In this study, a nanosecond-pulsed discharge plasma is employed to modify the macroporous XAD-2 resin to improve the adsorption performance of polycyclic aromatic hydrocarbons. After modification, XAD-2-20 resin shows great advantage on naphthalene (Nap) adsorption, whose adsorption capacity increased by 80.6% and 43.5% compared with the raw ...

A detailed procedure using non-ionic macropourous XAD-8 and XAD-4 resins is pre-sented for the isolation and fractionation of aerosol water-soluble organic compounds (WSOC) from aerosol samples.

Apr 30, 2015 · This review presents an overview of the various works done on the modification of Amberlite XAD resins with the objective of making it an efficient sorbent. The methods of modifications which are...
