Removal of Sr(II) with acrylamide modified attapulgite (AMATP) from aqueous solutions was investigated. The AMATP was characterized by XRD, SEM and FTIR and the pH with Sr(II) initial concentration were controlling factors for Sr(II) sorption process. The inhibitory effects of coexisting ions have the order as Ca2+> Mg2+> Na+. The sorption process of Sr(II) on AMATP was spontaneous and endothermic and followed the pseudo second-order sorption model and fit well with the Langmuir isotherm. Owing to its high sorption capacity and low cost, AMATP can be a promising candidate for Sr(II) sorption removal.
