Removal of methylene blue dye and heavy metal ions from aqueous solution with synthetic poly(Acryl amide-co-Acrylic acid)/MCM-41

The nanocomposites of poly (Acryl amide-co-Acrylic acid) with different contents of MCM-41 were prepared using ammonium persulfate as an initiator and N, N′-methylene bisacrylamide as the crosslinker. The optimum molar ratio of initial materials for preparation of poly (AAm-co-AAc) considered at prior work in our laboratory. Several nanocomposites with different amount of MCM-41 were prepared by radical graft copolymerization. The composites were characterized by XRD and the structure of nanocomposite materials was studied with FT-IR that showed the interaction between mesoporous material and poly (AAm-co-AAc). The TGA results indicated higher stability for poly (Acryl amide-co-Acrylic acid)/MCM-41composite than poly (AAm-co-AAc). The adsorption and desorption behavior of methylene blue were investigated for nanocomposites
