synthesis and characterization of poly (aam-co-aac)/naa nanocomposite and removal of methylene blue with it

the nanocomposites of poly (acryl amide-co-acrylic acid) with different contents of naazeolite were prepared using ammonium persulfate as an initiator and n, n′-methylenebisacrylamide as the crosslinker. the morphology was characterized by sem and the structure ofnanocomposite materials was studied with xrd and ft-ir that showed the interaction betweenporous materials and poly (aam-co-aac). the adsorption behaviors of methylene blue wereinvestigated for nanocomposites. it was shown that poly (aam-co-aac)/naa nanocompositeshave higher adsorption than naa and poly (aam-co-aac) alone. this effect was attributed togood interaction between the hydroxyl group in porous materials and carboxylic group in poly(aam-co-aac) with methylene blue.
