Acrylic acid (AA) was grafted onto the powdered isotactic polypropylene (i‐PP) with the electron‐beam‐induced preirradiation method (Chen, D.‐T.; Shi, N.; Xu, D.‐F. J Appl Polym Sci 1999, 73, 1357–1362). Some rare earth ions, including Sm 3+ , Nd 3+ , Eu 3+ , Gd 3+ , and Er 3+ , were adsorbed onto the grafting product PP‐ g ‐AA. The properties of Sm 3+ adsorbed were investigated in detail. These properties include the influences of the adsorption time, acidity, ion concentration of the solution, grafting yield of AA onto i‐PP, and temperature on the quantity and efficiency of the ion adsorption. Some kinetic and thermodynamic equilibrium constants of the adsorption were obtained in the experiments. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 76: 1549–1553, 2000
