POLYMER BEAD CONTAINING IMMOBILIZED METAL EXTRACTANT |
摘要 |
<p>Polymer beads are prepared containing an immobilized extractant for sorbing metal contaminants at concentrations of less than 1 mg/L in dilute aqueous solutions. A preferred polymer is polysulfone and the extractant can be a biomass material or a synthetic chemical compound sorbed into activated carbon. The polymer beads are prepared by dissolving the polymer in an organic solvent to form a solution, adding the extractant to the solution to form a mixture and injecting the mixture through a nozzle into water to form the beads.</p> |
