Acrylic acid (AA) was grafted onto the powdered isotactic polypropylene (i-PP) by using the electron-beam-induced preirradiation method.Eleven rare earth ions
including La3+
Pr3+
Nd3+
Sm3+
Eu3+
Gd3+
Tb3+
Dy3+
Er3+
Tm3+ and Yb3+
were adsorbed on the graft product PP-g-AA.The properties of RE3+ adsorbed were investigated in detail.These properties include the sorption quantity
the distribution ratio and the sorption rate.We found that “Inclined W Effect” and “Tetrad Effect” exist in the sorption behavior.
