Composites of layered double hydroxides( LDHs) and graphene (G) are excitingn anomaterials because of their uniques urface structures and excellent physicochemical properties. Such materials offer the advantages of both components,t hat is, the large surfacea rea and ample functional groups of graphene and the outstanding layered structure and ion-exchangeability of layered double hydroxides, whilst effectively avoiding the coagulation of graphene and the instability of pristine layered double hydroxides,a nd they have been widelyi nvestigated for applications in water remediation. This Minireview begins by summarizing the most common methods for the synthesis of G@LDH composites, including hydrothermalt reatment, coprecipitation, and in situ growth. Then, we review the adsorption and catalytic ability of G@LDH materials in the removal of contaminants from water,s uch as heavy metal ions, radionuclides, dyes, and other organic pollutants. Finally,w ed iscusst he challenges and offer ap erspective on the directions of future research of G@LDH composites.

“…Polymer composites are defined as a combination of polymers with other organic or inorganic materials to provide new material with target properties, like low density, toughness, stiffness, thermal behavior, chemical and mechanical stability, and other specific properties depending on the target of use. A lot of polymer composites were introduced with significant use in water treatment and desalination, including graphene-based composites, carbon-based composites, and clay-based composites [1][2][3]. e polymer composite research was offered due the need for materials with better adsorption and removal characteristics of metal ions, dyes, and other toxic pollutants.…”

Over the past five years, a lot of research activities in polymer composites were done in order to improve environmental sustainability and to present advantages for commercial applications of water treatment and desalination. Polymers offered tunable properties, improved processability, remarkable stability, high surface area for fast decontamination, selectivity to eliminate different pollutants, and cost-cutting of water treatment. Hence, the development of polymeric materials is one of the future directions to meet the environmental water standards and to supply the water requirements of the growing populations. This review highlighted the very recent achievements in fabrication, characterization, and applications of polymeric composites used for water treatment and desalination. The polymeric modifications, the addition of functional groups, and the assemblies of nanomaterials were also discussed in detail. In particular, great attention was paid to the recent advances in polymer/polymer composites, polymer/carbon composites, and polymer/clay composites, presenting their usage in the removal of various types of contaminants, e.g., metal ions, dyes, and other toxic pollutants. The review also summarized the main advantages and disadvantages of the different adsorbent materials. Specific attention was paid to the mechanism of adsorption, including chemisorption and physisorption mechanisms. In addition, the challenges and the future perspectives were identified to reach the optimal performance of the different adsorbents.

“…Up to now, several materials such as polymeric nanoparticles, micelles, metal clusters, nanoparticles, mesoporous silica and different carbon nanostructures have been investigated as adsorbent materials However, the limitation of these adsorbents such as low drug adsorption capacities, uncontrolled release and toxicity have restricted their development . To choose a desirable drug adsorption material, several important factors including high drug adsorption capacity, controlled drug release, and chemical stability especially water stability might be investigated .…”

A robust and highly water stable series of UiO‐66‐drived MOFs including UiO‐66‐NH2, glycidyl methacrylate functionalized UiO‐66‐NH2 (UiO‐66‐GMA) and ethylenediamine functionalized UiO‐66‐NH2 (UiO‐66‐EDA) were synthesized solvothermally and studied their adsorption performances toward two anti‐cancer drugs, methotrexate (MTX) and curcumin (CUR) in the case of overdose. It was found that functionalizing the surface of UiO‐66‐NH2 nanoparticles with different functional groups remarkably changes the adsorption capacity and the ideal adsorption selectivity of MTX over CUR. Particularly, the UiO‐66‐EDA exhibited the highest adsorption capacities for both drugs, 540.78 and 423.85 mg/g for MTX and CUR, respectively, because of the strong interaction between drug molecules and adsorbent via hydrogen bonding due to the existence of different polar functional groups. The kinetics of drugs adsorption was investigated by three well‐known kinetic models, which the output indicates that the adsorption of both drugs onto the synthesized MOFs follow the pseudo‐second‐order model. Moreover, it was found that the equilibrium adsorption results were well fitted with the Langmuir isotherm models, revealing that the adsorption of both drugs onto the synthesized MOFs is a monolayer adsorption process. Further investigation illustrated that the synthesized MOFs could be easily activated and reused after four successive adsorption–desorption cycles. The output of the present work is of main important for biomedical and environmental applications of MOFs as an outstanding adsorbent for adsorption removal of hazardous drugs from contaminated aqueous solutions.
