Abstract
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.
