Abstract :
The nanocomposites of poly (Acryl amide-co-Acrylic acid) with different contents of NaA
zeolite were prepared using ammonium persulfate as an initiator and N, N′-methylene
bisacrylamide as the crosslinker. The morphology was characterized by SEM and the structure of
nanocomposite materials was studied with XRD and FT-IR that showed the interaction between
porous materials and poly (AAm-co-Aac). The adsorption behaviors of methylene blue were
investigated for nanocomposites. It was shown that poly (AAm-co-AAc)/NaA nanocomposites
have higher adsorption than NaA and poly (AAm-co-AAc) alone. This effect was attributed to
good interaction between the hydroxyl group in porous materials and carboxylic group in poly
(AAm-co-AAc) with methylene blue.
