文摘

Composite hydrogels were synthesized from Tragacanth gum and graphene oxide. Hydrogels were characterized by FT-IR, FE-SEM, EDS, XRD, and TGA. Adsorption capacity was 142.50, 112.50 and 132.12 mg g−1for Pb(II), Cd(II), and Ag(I). Adsorbed Ag(I) ions in hydrogel were transformed to Ag0 nanoparticles by flower extract. Antibacterial performance of hydrogel containing Ag0 nanoparticles was examined.
