POLYMER SORBENT FOR ION RECOVERY PROCESSES

摘要

A process for the selective removal of ions from dispersion of solids in solutions and which also relates to coarse open cell polymeric foams which support ion exchange sites. The process for the selective removal of ions from a solution having solid materials dispersed therein comprises passing the solution having solid materials dispersed therein through a bed of coarse open cell polymeric foam having ion exchange sites. The ion-selective coarse open cell polymeric foam has a cell size sufficient to allow solutions having solids dispersed therein to pass through said foam.
