“…Other sorbents, less frequently used are: grained carbon (graphite), 5 polyurethane foam, 6 polyoctadecylosilane (Sep-Pak), 7 polytetrafluoroethylene (Chromosorb T) 8 and polypropylene. 9 The problem of humic substances isolation from water has only recently become important, since they are the precursors of harmful substances formed during water chlorination.…”

In this paper the results on the isolation of organic water pollutants by nonionic sorbents are presented. Polish active carbon Z4S, Amberlite XAD-2, XAD-4, XAD-7 and Polish nonionic macroporous sorbents were used. Adsorption effectiveness, as influenced by organics polarity and concentration, by contact time and by filtered water volume was examined. The best parameters for isolation with macroporous nonionic sorbents were established. For the desorption of organic substances, a Soxhlet extraction for 12hrs with dichloromethane is proposed. The investigated sorbents give total recoveries very close to those obtained by Amberlite XAD resins.

We report the fundamental chromatographic retention properties of spongy monolith that was previously reported as a novel separation medium for the effective pretreatment of environmental pollutants. According to the detailed examination on liquid chromatographic evaluations using hydrophobic, hydrophilic, and polyaromatic compounds as solutes, the spongy monolith consisted of poly(ethylene-co-vinyl acetate) and having macroporous co-continuous structures showed the selective retention ability for polyaromatic hydrocarbons (PAHs), especially coplanar compounds, whereas lower selectivity was observed for typical hydrophobic and hydrophilic compounds compared with the commonly used C18 medium. Moreover, we demonstrate the effective preconcentration of benzo[a]pyrene using a spongy monolith as a pretreatment column of an online column switching HPLC system.
