Efficient removal of heavy metals and other toxic metal pollutants from wastewater is essential to protect human health the surrounding vulnerable ecosystems. Therefore, significant efforts have been invested in developing practical sustainable tools address this issue, including high-performance adsorbents. In respect, within last few years, graphene-based aerogels/xerogels/cryogels (GBAs) emerged drawn attention as excellent materials for removing recovering harmful valuable different aqueous media. Such an upward trend mainly due features aerogel combined with properties graphene derivatives aerogel's network, GBAs' unique three-dimensional (3D) porous structure, high porosity, low density, large specific surface area, exceptional electron mobility, adjustable rich chemistry, remarkable mechanical features, tremendous stability. This review offers a comprehensive analysis fundamental aspects phenomena related application GBAs removal. Herein, we cover all types (bottom-up) synthesized GBAs, true microporous aerogels well 3D open-cell interconnected mesoporous macroporous aerogels, foams, sponges. Indeed, provide insights into understanding suitability such important by revealing mechanisms involved factors inducing controlling highly selective behavior these distinctive Besides conventional adsorptive pathways, critically analyzed ability electrochemically capture (i.e., electrosorption) their efficiency detoxification through reductive adsorption-reduction-readsorption). We also covered reusability aspect (GAs)-based adsorbents, which strongly linked outstanding stability efficient desorption captured metals. Furthermore, view numerous environmental benefits, development magnetically recoverable GAs highlighted. Moreover, shed light on potential scalable implementation evaluating performance continuous processes while highlighting versatility demonstrated remove multiple contaminants along Finally, provides readers accessible overview critical discussion major recent achievements regarding applications GAs-based adsorbents ions Along our recommendations suggestions future work new research directions opportunities, aims serve resource researchers field treatment inspire further progress towards next-generation expanding application.

To address the worsening water scarcity resulting from growing worldwide population's increased demand for potable and restricted availability of sources, it is necessary to eliminate contaminants wastewater. This will enhance quality available use in various sectors free up drinkable water. Adsorption one simple, efficient, cost-effective ways remove However, many previously used adsorbent materials have issues such as low selectivity, poor regeneration ability, lack functional modifications, high swelling, name a few. In this study, authors aimed adsorption malachite green by using novel nanocomposite (β-CDPZF) based on β-Cyclodextrin (β-CD) polymer containing Zinc ferrite (ZF) nanofiller. The study compared efficiency both (MG) Congo red (CR). β-CDPZF was characterized analytical techniques Fourier transform infrared (FTIR) spectroscopy, powder X-ray diffraction (XRD), dynamic light scattering (DLS), Brunauer–Emmett–Teller (BET) surface area analyzer, field emission scanning electron microscopy (FE-SEM), thermogravimetry (TG) analysis. investigated influence experimental conditions process, isotherm, kinetics, thermodynamic parameters determined adsorption. results showed that had fourteen times higher capacity (Langmuir) removal MG CR. Additionally, could be effectively five reuse cycles while retaining >90% MG. Therefore, can serve cost-effective, less swellable, efficient cationic dye.

The adsorption property of the costless green cellulose acetate (CA) was boosted by dual modifications: inner modification incorporating carboxylated graphene oxide (COOH-GO) into CA spheres and outer surface COOH-GO@CA iminodiacetic acid (IDA) for removing Pb(II). experiments Pb(II) proceeded in a batch mode to evaluate COOH-GO@CA@IDA spheres. maximal capacity attained 613.30 mg/g within 90 min at pH = 5. removal reached its equilibrium 20 min, % almost 100% after 30 low concentration. mechanism proposed according kinetics isotherms studies; addition, zeta potential (ZP) measurements X-ray Photoelectron Spectroscopy (XPS) analysis defined pathways. By comparing XPS spectra authentic used COOH-GO@CA@IDA, it deduced that contributed chemical pathways are Lewis acid-base, precipitation, complexation. demonstrated electrostatic interaction participation adsorbing cationic species onto negatively charged (ZP 14.2 mV 5). unique channel-like pores suggested pore-filling promising results superb recyclability character enable extend bench scale industrial scale.
