“…In the recent study, AMPS grafted TG with PVA chains were used for the preparation of beads containing silver nanoparticles along with GO. [ 61 ] The AMPS monomer having strongly ionizable sulfonic acid groups for metal ion coordination was used to graft on the macromolecular chains of TG. Green synthesized silver nanoparticles were stabilized by grafted hydrogel matrix and the presence of GO in the matrix increase the swelling ability and adsorption capacity of the adsorbents toward different metal ions due to the presence of different hydrophilic and chelating groups.…”

Tragacanth gum is a novel polysaccharide which offers interesting features in terms of high hydrophilicity, good biocompatibility, and biodegradability. The engineering of hydrogels requires careful designing of their macromolecular structures so that desirable features may be incorporated into the material. Graft polymerization has come up as an interesting approach to develop molecules for drug delivery, wound care systems, and infection‐resistant materials. The most important aspect of graft functionalization is the proper control over physico‐chemical properties of the grafted matrix. The extent of functionalization may be governed by the grafting parameters and may lead to the chemical designing of the molecule in a controlled manner. This opens up enormous possibilities of developing materials for a wide range of applications as advanced materials.

“…FTIR spectra of both TG and catalyst hydrogel showed bands in the range of 3400–3500 cm −1 (asymmetric stretching of O−H group). However, after interaction of TG with cross‐linking agents and nanocomposite, comparatively broader spectral band was observed for catalyst hydrogel …”

“…Presence of functional groups such as, carboxyl and hydroxyl facilitates the interaction of TG with different cross‐linking agents and monomers to form TG hydrogels . Being naturally abundant, non‐toxic, biocompatible and stable over a wide pH range, it has been applied for the fabrication of hydrogel‐based biomaterials for medical applications . Furthermore, TG holds approval by USA GRAS in 1961 for their application in food and pharmaceutical industries .…”

Tragacanth Hydrogel Integrated CeO₂@rGO Nanocomposite as Reusable Photocatalysts for Organic Dye Degradation

Sunlight‐driven photocatalytic degradation has attracted great attention to tackle the issue of water contaminating organic dyes. As a proof of concept, we propose that nanoceria (CeO2) decorated on the surface of reduced graphene oxide (rGO), could effectively degrade pollutant organic dyes namely methylene blue (MB) and congo red (CR), when exposed to sunlight. The formation of as‐synthesized nanocomposite (CeO2@rGO) was monitored using UV‐visible, Fourier transfer infrared (FTIR) and RAMAN spectroscopy, X‐ray diffraction (XRD), Photoluminescence (PL), and Field emission scanning electronic microscopy (FESEM). Time‐dependent dye degradation was observed for up to 5 h and followed Langmuir‐Hinshelwood first‐order kinetics. Notably, at equivalent concentrations (2 mg), CeO2@rGO exhibited enhanced degradation of MB (∼92 %) and CR (∼83 %) dyes when compared to bare CeO2. The photocatalytic efficiency of CeO2@rGO was further enhanced by integrating in a polymer hydrogel fabricated using tragacanth (TG), a natural gum. The hydrogel photocatalyst (CeO2@rGO‐TG) exhibited ∼91 % MB degradation, at half the amount of CeO2@rGO in free form. More importantly, CeO2@rGO‐TG could be easily separated from the dye solution and re‐employed for multiple cycles of degradation.

“…The critical micelle concentration (cmc) and surface tensions were determined as the values of the break point of surface tension versus logarithm concentration plots. From figure (7), the cmc of both surfactants (3) and (4) were found to be 0.0005 and 0.00141 mN m -1 , respectively [31].…”
