Özet

Polyacrylamide (PAA)-bentonite (B) and zeolite (Z) composites were prepared by direct polymerization of PAA in suspensions of B and Z. Phytate (Phy) immobilized onto the composites to obtain their Phy modifications. FT-IR and XRD were employed to characterize their structures. The sorption of Pb2+ from various adsorption media onto the composites was then investigated. The reusability and storage characteristics of the adsorbents with and without Phy were also considered for Pb2+ adsorption.
