Chemically modified polymeric resins for high performance liquid chromatography, solid-phase extraction and organic separation by LC and GC
… on PS/DVB resin. On the hydrophilically modified resins, the capacity factors (k[superscript]') of polar compounds (such as phenol, p-cresol) are increased, while the k[superscript]' of non-polar compounds (such as toluene, cumene) are decreased. The opposite is true for hydrophobically modified …

Removal of organic contaminants from aqueous systems
… MN200, acidic functionalised hyper-cross-linked polymeric resins MN500 and S957, and Granular Activated Carbon (GAC) were tested as sorbents. The results show the kinetics of adsorption, for all contaminants, follow pseudo-second order models with rates controlled by particle diffusion. For …

Processi di biorefining per l'estrazione di secondary chemical building blocks da sottoprotti dell'agro-industria
… in completely water based process, and polymeric resins with the aim of substituting secondary chemical building blocks with the same compounds naturally present in biomass. We characterized several industrial enzymatic product for their ability to hydrolize the different molecular …

Adsorption and membrane filtration for the separation and valorization of hemicellulose from organosolv beechwood hydrolyzates
… hemicellulose out of beechwood hydrolyzate. Four polymeric resins and one zeolite were compared in batch experiments, and competitive adsorption isotherms were modeled. The most efficient resin SP700 was studied in more detail in column tests. The adsorption of lignin and hemicellulose from …

Development of a Humidity-Resistant Coating to Impart High Oxygen Barrier Performance to Food Packaging Films
… are readily soluble in typically hydrophilic resins. In this work, we demonstrate a 1 – 2 micron thick oxygen barrier coating, prepared on a 12 micron poly(ethylene terephthalate) substrate, that has oxygen transmission rates as low as 1.44 cc m<sup>-2</sup> day<sup>-1</sup> under standard …
