  • Can carboxymethyl cellulose hydrogels be used to treat wastewater contaminated by heavy metal ions?
  • In recent years, the carboxymethyl cellulose (CMC) based hydrogels were rapidly developed, which demonstrate potential for the treatment of wastewater contaminated by heavy metal ions [ , , ]. Dahlan et al. prepared the CMC-grafted polyvinyl alcohol (PVA) magnetic hydrogel for the efficient removal of Cu II ions.
  • How are CMC-ECH/Pam hydrogels prepared?
  • Cite this: ACS Appl. Polym. Mater. 2025, 5, 3, 2070–2078 In this work, CMC-ECH/PAM hydrogels with perfect compressive strength were prepared by epichlorohydrin (ECH) cross-linking sodium carboxymethyl cellulose (CMC) grafted with polyacrylamide (PAM) to remove the copper ion (Cu 2+) from water.
  • Can polyacrylamide (PAM) be used in a hydrogel?
  • In this concern, we are considering to introduce polyacrylamide (PAM) into the hydrogel. First, PAM can easily be crosslinked by using N,N’- methylenebis (acrylamide) to form a strong hydrogel with controlled crosslinking density. Second, the side amine and carbonyl functional groups can act as binding sites for the metal ions.
  • How are polysaccharides based on sodium alginate and carboxymethyl cellulose formed?
  • The polysaccharides inner core based on sodium alginate (SA) and carboxymethyl cellulose (CMC), was formed by physical crosslinking with pH-sensitive property. The synthetic polymer out-layer with enhanced stability was introduced by chemical crosslinking to eliminate the expansion of inner core and the diffusion of inner content.
