Paper Title:
Adsorption Properties for Superabsorbent of Inverse Suspension Polymerization Poly(acrylate-Co-Acrylamide)
  Abstract

Superabsorbent polymers are lightly crosslinked, hydrophilic polymer network having many functional groups. The adsorption properties in heavy metal ion solutions using poly(acrylate-co-acrylamide)(PAAM) are investigated. It is found that PAAM has a high uptake to heavy metal ions, and that the adsorption of heavy metal ions is greatly influenced by pH and the initial solution concentrations. The biggest and the smallest amount of adsorption are Cu2+ and Cr3+ in CuCl2 and CrCl3 solution, respectively. It was feasible for selective adsorption of the metal ions in the solution onto PAAM hydrogel by controlling the pH values of the mixing solution for CuCl2, FeCl3, CrCl3. Langmiur equatiom can satisfactorily fit for the adsorption of Cu2+ while not fit for that of Fe3+ and Cr3+.
