Lead removal by polyacrylamide-bentonite and zeolite composites: Effect of phytic acid immobilization
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 Pb 2+...

| description | 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 Pb
2+ 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 Pb
2+ adsorption.
All isotherms were L and H type of the Giles classification. The Phy adsorption capacities (
X
M) of PAA-B and Z lower than those of bare B and Z due to their surface coverage by PAA. The Phy modification decreased the Pb
2+ adsorption capacities of B and PAA-B but ascended those of Z and PAA-Z. However, Phy significantly increased the Langmuir equilibrium constants (
K
L) for all adsorbents. Ionic strength of the adsorption media was favorable for the adsorption capacity of PAA-B while not for that of PAA-Z. The chemical structure of the composites was not changed after five reuses and the storage foregoing.
It is foreseen that the use of PAA-B and PAA-Z and their Phy modifications will provide practicality and effectiveness for Pb
2+ separation and removal procedures. The

M (mol

K
L (L
