@entity2975 ( @entity3880 )- @entity6638 (B) and @entity10091 (Z) composites were prepared by direct polymerization of @entity3880 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 @entity10781 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 @entity10781 adsorption. All isotherms were L and H type of the Giles classification. The Phy adsorption capacities (X(M)) of @entity3880 -B and Z lower than those of bare B and Z due to their surface coverage by @entity3880 . The Phy modification decreased the @entity10781 adsorption capacities of B and @entity3880 -B but ascended those of Z and @entity3880 -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 @entity3880 -B while not for that of @entity3880 -Z. The chemical structure of the composites was not changed after five reuses and the storage foregoing. It is foreseen that the use of @entity3880 -B and @entity3880 -Z and their Phy modifications will provide practicality and effectiveness for @entity10781 separation and removal procedures. The X(M) (mol kg(-1)) and K(L) (L mol(-1)) values for @entity10781 adsorption from a model solution were 0.16 and 3625 for @entity3880 -B, 0.18 and 5.1 x 10(5) for @entity3880 -B-Phy, 0.28 and 13210 for @entity3880 -Z and 1.65 and 2.0 x 10(5) for @entity3880 -Z-Phy.
