estimated using the Langmuir, Freundlich, and Langmuir–Freundlich isotherm
models. The Langmuir model was the best-fitting for all applied nanomaterials. In
addition, the kinetics were analyzed by using pseudo-first-order, pseudo-second
order, and intraparticle diffusion models, and the pseudo-second-order model was
an apparent fit for all three applied nanomaterials. The maximum Adsorption
capacity toward MB obtained from the materials was in the order zeolite/LDH
composite > zeolites > Zn-Fe LDH. Thus, the zeolite/LDH composite is an
excellent adsorbent for the removal of MB from polluted water. The first material
was Layered double hydroxides constitute (LDHs) ,second applied material was
Zeolites which naturally occurring porous crystalline alumino-silicate with three
dimensional structures and third material was LDH-zeolite composite. They were
shown to exhibit antibacterial activity against Gram-positive bacteria ,gram
negative bacteria and a fungal strain (Candida albicans ATCC 60913).
