【発明の名称】固定化金属抽出剤含有ポリマービーズ
Document Type and Number:
Japanese Patent JPH03504467
Kind Code:
A
Abstract:
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.
