Abstract

The advances in using polyurethane foam sorbents for chemical preconcentrations and separations are systematized and reviewed for the 1983-1988 period. The new achievements are ordered in tables split according to the status of the polyurethane foam sorbent i.e. untreated membranes, swollen membranes and membranes modified by chemical anchoring, and to the phase from which the separation or preconcentration is achieved (liquid-solid and/ or gas-solid transfer). The importance of the membrane structure of polyurethane foams in allowing faster sorptions from liquid and gas phases is also stressed.
