Claims17
A method for the manufacture of a sorbent comprising at least one weakly basic ion exchange resin, a ferro-magnetic substance, and a water permeable organic polymer binder, which method comprises
- (a) mixing together said resin, said ferromagnetic substance, said binder, and an organic solvent capable of dissolving said binder thereby forming a malleable mixture, said binder being selected from the group consisting of cellulose esters and cellulose ethers;
- (b) removing said solvent from said mixture to obtain a dry solid;
- (c) forming said solid to the desired size and shape;
- and
- (d) recovering the resultant sorbent.
