Description
Summary:Porous organic sorbents containing primary amino groups and crosslinked with divinylbenzene or ethyleneglycol dimethacrylate were used for the recovery of various organic pollutants from aqueous solutions. The kinetics of sorption of these solutes is dependent on the specific area and the average pore radius of the sorbent. Physical sorption and chemical interaction of the acid solutes with the amino functions are both involved in the sorption process. The variation of the sorption capacity with the specific area of the solute depends on the nature of the solute. Experiments with mixtures of organic solutes show that the sorption of a given solute may be increased or decreased by the presence of another one. The capacity is increased during cycles of using and regenerating the sorbent. © 1994 John Wiley & Sons, Inc.
