“…Its sorption capacity was 357 mg/g for an extraction time of 33 min. The protective effect of chitosan was also used for preparation of embedded 1,5-diphenylcarbazone grafted magnetic GO with magnetic chitosan [ 61 ]. According to the authors, this effect could be attributed to the increasing chitosan polymer rigidity using glutaraldehyde as a the cross-linker reagent.…”

Direct determination of lead trace concentration in the presence of relatively complex matrices is often a problem. Thus, its preconcentration and separation are necessary in the analytical procedures. Graphene-based nanomaterials have attracted significant interest as potential adsorbents for Pb(II) preconcentration and removal due to their high specific surface area, exceptional porosities, numerous adsorption sites and functionalization ease. Particularly, incorporation of magnetic particles with graphene adsorbents offers an effective approach to overcome the separation problems after a lead enrichment step. This paper summarizes the developments in the applications of graphene-based adsorbents in conventional solid-phase extraction column packing and its alternative approaches in the past 5 years.

“…The final black solution was filtered and washed with distilled water until obtaining a pH 7 in the filtrated solution. Besides, Ghorbanian et al [80] reported the synthesis of a magnetic nanocomposite with GO and a chitosan matrix functionalized with 1,5-diphenylcarbazone (DPC) and magnetite for lead extraction from water. GO 7 Adsorption Science & Technology was prepared with a modified Hummers and Offeman method where graphite powder was poured into a 9 : 1 mixture of concentrated H 2 SO 4 /H 3 PO 4 (360 : 40).…”

This review covers the preparation, characterization, and application of magnetic adsorbents obtained from carbon-based sources and their application in the adsorption of both inorganic and organic pollutants from water. Different preparation routes to obtain magnetic adsorbents from activated carbon, biochar, hydrochar, graphene, carbon dots, carbon nanotubes, and carbon nanocages, including the magnetic phase incorporated on the solid surface, are described and discussed. The performance of these adsorbents is analyzed for the removal of fluoride, arsenic, heavy metals, dyes, pesticides, pharmaceuticals, and other emerging and relevant water pollutants. Properties of these adsorbents and the corresponding adsorption mechanisms have been included in this review. Overall, this type of magnetic adsorbents offers an alternative for facing the operational problems associated to adsorption process in water treatment. However, some gaps have been identified in the proper physicochemical characterization of these adsorbents, the development of green and low-cost preparation methods for their industrial production and commercialization, the regeneration and final disposal of spent adsorbents, and their application in the multicomponent adsorption of water pollutants.
