“…Further, the quantitative dye removal efficiency (% R e ) and dye adsorption capacity ( q e , mg g –1 ) of G3 were determined with the help of the calibration curves of EB (Figure S34A,B), and the values were found to be 95.8% and 66.7 mg g –1 , respectively, after 48 h of incubation, which is comparable to our recently reported hydrogels based on acrylamide/2-hydroxyethyl methacrylate and the IL cross-linker and other dye adsorbents also. ,, In the case of SZ adsorption, the % R e and q e values after 48 h, as determined from the corresponding calibration curves (Figure S34C,D), were found to be 84.3 and 66.9 mg g –1 , respectively. These values are very close to those of other reported adsorbents or reagents utilized for the treatment of removal of SZ from wastewater. , Such kind of dye absorption was mostly caused by the Columbic interactions between the cationic cross-linkers present in the gel and negatively charged dye/drug molecules in solution …”

“…Ionic hydrogel-based materials are well-known for their potential applications in drugs/dyes-adsorption and wastewater treatment. ,− To explore such possibilities for this cationic G3 hydrogel, we examined its removal efficiency toward EB dye and SZ drug via UV–vis spectroscopy. The result showed that the absorbances at λ max,EB = 520 nm and λ max,SZ = 359 nm for EB and SZ, respectively, decreased drastically within 24 h, as could be seen clearly from the UV–vis spectra of the supernatant dye solutions before and after charging with G3 (Figure A,B).…”

The rising development in the field of synthetic-functionalized polypeptides aids in the generation of advanced biomaterials comprising versatile functionalities, enabling them to be potential candidates for their progressive applications in different areas. Thus, in this work, the ring-opening polymerization (ROP) of a designed acryloyl-L-serine N-carboxyanhydride (SerA NCA) monomer is conducted to produce side-chain acryloyl-functionalized poly(acryloyl-L-serine) [P(AcSer)] for its facile and selective functionalization to introduce zwitterionic and amphiphilic groups for stimuliresponsiveness as well as gelability via Michael addition and radical polymerization. The postfunctionalization of P(AcSer) with L-cysteine (Cys) leads to the formation of the zwitterionic polypeptide, P(AcSer)-g-Cys, which has an isoelectric point (pI) of 2.7. Near the pI, the aqueous P(AcSer)-g-Cys solution exhibits pH-responsiveness (pH ranges of 2.2−4.1), transforming the transparent solution to a cloudy suspension containing insoluble hierarchical nanoaggregates of various dendritic morphologies. Notably, this cloudy suspension undergoes a upper critical solution temperature (UCST)-type phase transition with tunable cloud points, transforming it into a clear solution upon heating. The addition of triethylene glycol monomethyl ether thiol (MTEG-SH) to P(AcSer) produces amphiphilic P(AcSer)-g-MTEG, which forms vesicular nanoassemblies in water and is capable of encapsulating hydrophobic Nile red (NR) dye present in water. Apart from that, grafting of MTEG moiety introduces lower critical solution temperature (LCST) property to P(AcSer)-g-MTEG in water. Thiol-based cross-linkers and ionic-liquid-based cationic cross-linker are employed for the gelation of acryl-functionalized P(AcSer). The obtained polypeptide gel materials exhibit excellent swelling behaviors in organic/aqueous media. Additionally, the cationic polypeptide gel shows profound dye adsorption capacity under exposure to the aqueous solution of eosin B and sulfasalazine.

“…In the study of Bouallegue et al [67], a biosorbent from pomegranate peels (PG) was produced for the removal of sulfasalazine (SSZ), a pharmaceutical used to treat diseases such as rheumatoid arthritis and Crohn's disease. According to the results, maximum removal (100%) was achieved at pH 4.8, with 50 mg/L as the initial concentration of SSZ and an adsorbent dose of 0.5 g/L within 60 min.…”

Wastewater treatment has attracted much attention in recent years as a potential source of water, and there are some concerns about its safety for human use. Eco-friendly and cost-effective adsorbent materials were successfully synthesized from several peels, such as orange, banana, pomegranate, avocado, kiwi, etc., and were used as natural adsorbents or as activated carbons derived from these peels for water and wastewater treatment. In this review, the latest research focusing on the effective modification of these peels for the removal of several pollutants found in wastewaters are summarized and compared, such as pharmaceuticals, dyes, heavy metals, and anions that are released in waste and have a negative impact on human and animal health. In this review, focus is given to activated carbon produced from fruit peels. Moreover, fruit peels as adsorbent materials, without previously being converted to activated carbon, are of limited use in the recent literature.

“…[4][5][6][7] Despite their efficiency, these processes are limited in face of high toxicity and high levels of biorecalcitrant pollutants. Physical processes have been adopted for the removal of pharmaceutical pollutants including adsorption onto activated carbon, [8] metal oxide-based materials, [8] clay materials, [9] agroindustrial wastes, [9,10] biochar, [9] modified chitosan, [9,11] etc., and membrane processes such as reverse osmosis, [12] nanofiltration, and more. [13,14] However, these processes have the drawback of removing and transferring the pollutant from one phase to another, which involves a posttreatment step.…”

The degradation of levofloxacin, a pharmaceutical pollutant model has been studied by gliding arc plasma (Glidarc). In this work, a full factorial design was applied to investigate the influence of the operating parameters and their interactions on the degradation yield. This experimental design demonstrates that the electrode-solution distance is the most influential factor followed by the concentration of levofloxacin and the applied voltage. Response surface methodology using Doehlert design was adopted to predict the optimal conditions of the plasma treatment. Results showed that for an applied voltage of 7.2 kV, an electrode-solution distance of 2.7 cm, and an initial concentration of 45.6 mg L −1 , the degradation yield reached 52.81 ± 1.19% after 90 min of plasma treatment, which corresponds to an energy yield of 40.1 mg kW −1 h −1 .In addition, to develop a cost-effective system for the degradation of pharmaceutical pollutants, biodegradability of the plasma pretreated solutions was evaluated. Resultsshowed that a readily biodegradable solution was obtained after only 30 min of plasma pretreatment. Hence, the feasibility and the efficiency of coupling plasma to biodegradation processes were confirmed. Moreover, coupling plasma to photocatalysis was carried out and results showed that 45 min of plasma treatment followed by 40 min of photocatalytic treatment achieved 100% degradation that neither the plasma process nor the photocatalysis process can reach alone.
