Poly(sodium acrylate), polyacrylamide and their copolymers were introduced into the interlayer spaces of raw montmorillonite (Mt) by in-situ polymerization. The obtained clay polymer nanocomposites (CPN) retained the layered structure. The polymers were intercalated at an intended polymer-to-clay mass ratio of 1:1. Differences in the mechanism of decomposition of samples depended on the type of polymer functional groups. The CPN were tested as adsorbents of Fe3 + ions. The highest adsorption capacity was achieved for samples containing poly(sodium acrylate), which was due to their high swelling capacity and the attraction of iron ions by carboxyl groups.
► Clay mineral/poly(sodium acrylate-co-acrylamide) hydrogel nanocomposites were studied. ► A relatively high amount of raw montmorillonite was introduced to the CPN. ► Effect of polymer composition on the thermal stability of CPN was observed. ► Swelling and adsorption capacity was determined by the hydrogel type. ► High adsorption efficiency in Fe(III) removal was achieved for the studied CPN.
