Highly efficient macroporous adsorbents for toxic metal ions in water systems based on polyvinyl alcohol–formaldehyde sponges

Abstract

A series of macroporous adsorbents based on polyvinyl alcohol–formaldehyde (PVF) sponges was prepared using redox-initiated grafting polymerization of acrylamide (AM) followed by hydrolysis under alkaline conditions, and used as efficient macroporous adsorbents in water medium.
