Influence of crosslinking degree on Cu(II) and Fe(III) adsorption capacity of hydrogel/montmorillonite composites
Wpływ stopnia usieciowania na pojemność sorpcyjną kompozytów hydro-żelowo-montmorylonitowych względem kationów Cu(II) i Fe(III)
hydrogel
poly(acrylic acid)
polyacrylamide
montmorillonite
polymer composites
Intercalation of polyacrylamide (PAAm) and poli(acrylic acid) (PAA) into interlayer spaces of natural montmorillonite by the in situ polymerization technique was studied. The modificationswere carried out with using both the raw and pre-treated clay. Itwas shown that no initial modification of the layered mineral (by ion-exchange with Na+ cations or organophilization) is needed for the successful introduction of hydrogels into the interlayer gallery. The effect of kind of polymer and its crosslinking degree (withN,N‘-methylenebisacrylamide, MBA) on the structure of the obtained composites was investigated. The polyacrylamide-containing materials exhibited a tendency to the formation of exfoliated structure. Finally, the composites were tested in a role of adsorbents in an elimination of transition metal cations (Cu2+ and Fe3+) from aqueous solutions. The highest adsorption capacity was achieved on the poly(acrylic acid)/montmorillonite composite with the hydrogel crosslinked with MBA at the MBA/monomer molar ratio of 0.01.
