| titleOfInvention |
Sulfur-containing aliphatic polymer for the selective absorption of dissolved metal species |
| abstract |
A sulfur-containing water insoluble hydrogel polymer for selectively removing trace amounts of dissolved metal species is produced from a reaction product of nitrilotriacetic acid (NTA) and polyethylenimine (PEI) which is then treated in a water-swollen state with carbon disulfide. The polymer has a physical configuration that facilitates formation of a porous stationary bed through which water can pass for treatment. |
