“…Various moieties (i.e., amine (–NH 2 ), hydroxyl (–OH), carboxyl (–COOH), and thiol (–SH)) on the surface of hydrogels can provide active binding sites and the 3D network structure can provide diffusion pathway to exhibit superior adsorption capacities and kinetics for the water pollutants [ 33 , 34 ]. Numerous biomaterials have been used for the fabrication of hydrogel-based adsorbents for wastewater treatment applications [ 33 ] and for pollutant removals such as chitosan [ 35 ], starch [ 12 ], xylan [ 36 ], sugarcane bagasse cellulose [ 20 , 37 ], biochar [ 12 ], or ulvan from green macroalgae [ 38 ]. However, when using an individual biopolymer it is more difficult to achieve high adsorption capacity and selectivity towards a specific pollutant or multicomponent adsorption.…”

“…Bioremediation and remediation processes come to assuage the contamination and promote environmental sustainability. In this way, hydrogels have a high potential for remediation with a substantial capacity for the adsorption of a wide range of pollutants such as toxic metals [ 12 , 13 , 14 , 15 ], organic compounds [ 16 , 17 ], dyes [ 18 , 19 , 20 ], and others.…”

Hydrogels have become one of the potential polymers used with great performance for many issues and can be promoted as biomaterials with highly innovative characteristics and different uses. Gelatin is obtained from collagen, a co-product of the meat industry. Thus, converting wastes such as cartilage, bones, and skins into gelatin would give them added value. Furthermore, biodegradability, non-toxicity, and easy cross-linking with other substances can promote polymers with high performance and low cost for many applications, turning them into sustainable products with high acceptance in society. Gelatin-based hydrogels have been shown to be useful for different applications with important and innovative characteristics. For instance, these hydrogels have been used for biomedical applications such as bone reconstruction or drug delivery. Furthermore, they have also shown substantial performance and important characteristics for remediation for removing pollutants from water, watercourse, and effluents. After its uses, gelatin-based hydrogels can easily biodegrade and, thus, can be sustainably used in the environment. In this study, gelatin was shown to be a potential polymer for hydrogel synthesis with highly renewable and sustainable characteristics and multiple uses.

“…Hydrogels are commonly used as promising scaffolds for wound dressings, 36 because they offer numerous attractive properties such as 3D microporosity, soft consistency, 37 exudation absorption potential, freezing wounds, and material-dependent bio-adhesiveness. They can be formed via chemical, enzymatic, thermal, or light-induced crosslinking between polymeric chains of molecules.…”

“…Nowadays, there are different techniques have been applied to eliminate antibiotics from aquatic system, such as oxidation 9 , adsorption and degradation 10 , 11 . Between these techniques, adsorption is cheap, simple, promising method for antibiotics, organic and inorganic contaminants removal from water 12 – 15 . The polymeric beads as adsorbent have been more favorable than the nanoparticles, film or fiber forms because of its easy fabrication, excellent dispersion, controllable size dimension and quick recovery process.…”

Adsorption efficiency of Cefotaxime by novel nanocomposites beads composed of iota carrageenan (IC), sulfonated poly vinyl alcohol (SPVA) and nano sulfated zirconia (SZrO2) was evaluated in this study. SZrO2 was synthesized from solvent-free and easy calcination technique then embedded with 1–2.5 wt.% into the polymeric matrix. A batch adsorption experiment was carried out to investigate the effects of dosage, pH, beginning concentration, and time on Cefotaxime antibiotic adsorption. The ideal conditions to achieve complete removal are 88.97 mg L−1 initial cefotaxime concentration at time 3.58 h with 11.68 mg of beads composite with 2.5 wt.% of SZrO2. The pseudo second order kinetics model better illustrated the adsorption of cefotaxime on nanocomposite beads, and the maximum adsorption capacity are 659 mg g−1 for the composite with 2.5 wt.% of SZrO2. The mechanism of adsorption process depend mainly on the interactions between the different functional groups of SPVA, IC and SZrO2. The nanocomposites beads also exhibit excellent reproducibility after ten adsorption cycles. This type of nanocomposites beads can be easily separated from water without leaving any residue, verifying this novel nanocomposite beads has strong potential in water treatment for the antibiotic contaminant removal.
