Sponge for the absorption of metal ions |
| abstract |
An open-celled cellulosic sponge contains a thermally insolubilized polyethyleneimine (PEI) capable of selectively removing dissolved ions from aqueous systems. By virtue of a cuboid configuration of critically selected dimensions, the insolubilized PEI is substantially uniformly distributed in useful amounts throughout the sponge. |
