摘要：

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 Sm3+, Nd3+, Eu3+, Gd3+, and Er3+,, were adsorbed onto the grafting product PP-g-AA. The properties of Sm3+ 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. (C) 2000 John Wiley & Sons, Inc.
