Abstract:
A bead is provided which consists essentially of peat moss immobilized by crosslinked neutralized poly(carboxylic acid) binder, sodium silicate binder, or polysulfone binder. The bead is effective to remove metal contaminants from dilute aqueous solutions. A method of making metal-ion-sorbing beads is provided, comprising combining peat moss or other nonliving biomass and binder solution (preferably in a pin mixer where it is whipped), forming wet beads, and heating and drying the beads. The binder solution is preferably poly(acrylic acid) and glycerol dissolved in water and the wet beads formed from such binder solution are preferably heated and crosslinked by radio frequency heating.
