Synthesis and fabrication of antibacterial hydrogel beads based on modified-gum tragacanth/poly(vinyl alcohol)/Ag highly efficient sorbent for hard water softening.

In the current study, hard water softening for the removal of Ca and Mg ions was performed using hydrogel beads based on Gum Tragacance (GT) modified by using 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and poly(vinyl alcohol). The antibacterial spherical hydrogel beads were fabricated by instantaneous gelation of well dispersed mixture of poly(AMPS)-g-GT (1 g), poly(vinyl alcohol) (PVA, 1 g) flocculent, green-synthesized silver metal nanoparticles (AgNPs, 10 mg), and graphene oxide (GO, 10 mg) in the acetone solution of boric acid and then transferring into the different amounts (0.5-2.

Preparation of spherical porous hydrogel beads based on ion-crosslinked gum tragacanth and graphene oxide: Study of drug delivery behavior.

In this study, new spherical pH-sensitive porous hydrogel beads were prepared based on the water-soluble gum tragacanth (GT) polysaccharide and graphene oxide (GO) nanosheets by using Ca and Ba ions as crosslink agents, calcium carbonate particles as solid porogen, and Rivastigmine (RIV) as a model drug. The prepared hydrogel beads were characterized by FE-SEM, XRD, FTIR, BET, and TGA techniques. The swelling behavior of the beads was affected by cross-linker content, type of cross-linker, composition of beads, and pH.

Synthesis of modified gum tragacanth/graphene oxide composite hydrogel for heavy metal ions removal and preparation of silver nanocomposite for antibacterial activity.

New composite hydrogels were synthesized based on gum tragacanth (GT) carbohydrate and graphene oxide (GO). GT was sulfonic acid-functionalized and cross-linked by using 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and N,N'-methylenebisacrylamide (MBA) monomers and ceric ammonium nitrate (CAN) as an initiator. The prepared hydrogels were characterized by Fourier transform infrared spectrum (FT-IR), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and thermogravimetric analysis (TGA).
