Fabrication of PVA/Ag Nanocomposite Hydrogels using Sol Gel Technique: Swelling and Removal of Chromium Ion Studies

Abstract

The PVA/Ag nanocomposite hydrogel with 3D network has been fabricated via sol-gel method. The fabricated nanocomposites were well characterized by FT-IR, SEM, TEM and XRD. The swelling equilibrium has also been observed with various pH medium. Parallel adsorption studies have also been carried out with a different time, pH and dosage of adsorbent. The maximum removal of chromium for this sample is greater than other compound. Therefore, in this PVA/Ag nanocomposite hydrogel has a potential tendency for the removal of hexavalent chromium ion from industrial effluent wastewater.
