Studies of authors on the adsorption and adsorption mechanisms of various organic compounds onto three types of polymeric adsorbents in aqueous solutions are reviewed.The investigations showed that the high adsorption capacity of the adsorbents to many organic compounds was ascribed not only to their high specific surface area but also their intensive micropore structure.The double-peak pore distribution mode

two-stage dynamic character and the formation mechanism of oxygen-containing groups on their surfaces are systematically studied.To bifunctional resin

the point of our study is on its industrial application.Macroporous resins and hypercrosslinked resins were modified with many different functional groups such as amidocyanogen

carboxyl

sulfonate etc.

to elevate their adsorption capacities.Some proposed applications of these bifunctional resins in industrial wastewater are presented.The observation on the acrylic ester resin is still on a preliminary stage in terms of its adsorption mechanism and application to organic industrial wastewater.The investigations showed that the matrix of acrylic ester resin and functional groups on its surface played an important role on its adsorption mechanism.
