“…LDH that is intercalated with sulfide has good absorption capacity for heavy metal ions, and its selective absorption has attracted wide attention, which will be described later [57,58]. In addition, LDH is mainly intercalated with organic molecules, which can significantly improve absorption capacity for heavy metal ions [59][60][61][62]. For example, compared with the maximum absorption capacity of LDH, the maximum absorption capacity of LDH intercalated with SDBS and citrate for Cu 2+ increased by 72.7 mg/g [63].…”

The use of functional material can help mitigate the pollution by heavy metals, which presents an array of risks to human production and life. This work provides a comprehensive review of the current knowledge on functionalized layered double hydroxide (LDH) as a heavy metal absorption material, by synthesizing the information from a total of 141 relevant publications published since 2005. LDH provides a potentially highly efficient method to adsorb heavy metal ions, which is simple to prepare and of low cost. The lack of functional groups and structural components of pristine LDH, however, limits the absorption capacity and widespread applications of LDH. Through intercalation, surface modification, or loading on substrates, functional groups or structural components are introduced into the pristine LDH to prepare functionalized LDH. In this process, the hydroxyl group and the valence state of [Mg(OH)6] octahedrons play a crucial role. Functionalized LDH can be endowed with selective absorption capacity and enhanced stability and recyclability. After adsorbing heavy metal ions, functionalized LDH can be readily separated from the liquid phase. These aspects are discussed, along with the structure and composition, shape and size, and synthesis methods and research tools of LDH. This work concludes with the discussion of preparation and utilization and a look to the future in terms of identified research needs regarding the preparation, use, and recycling (or upcycling) of economical and environmental-friendly LDH.

“…The results showed that with increasing the amount of PPE and DPE adsorbents up to 0.1 g/L, removal of arsenic increases and after that no appreciable increase was observed. The initial rise in adsorption of arsenic is due to more adsorptive sites and a high amount of adsorbent available for adsorption of the ions (Figure S1(b)) (Bessaies et al 2020).…”

Primary aliphatic or aromatic amino acids on Phyllanthus Emblica seed coat are derivatized in the form of N-substituted 2-sulfanylacetamide derivative. Pristine Phyllanthus Emblica (PPE) and derivatized phyllanthus emblica (DPE) products were used for removal of trivalent arsenic from aqueous sample. Thioglycolic acid and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimidehydrochloride (EDC) were used for derivatization process. Carboxylic group of thioglycolic acid reacts with EDC to form an activated ester leaving group which is displaced by nucleophilic attack of primary amino acids on seed coat. BET surface area (0.3152±0.0081 m2/g) and Langmuir surface area (0.3571±0.0054 m2/g) of PPE are changed after modification. DPE showed high surface area compared to un-derivatized adsorbent due to presence of more modified groups on the surface (BET surface area 0.5812 m2/g, Langmuir surface area 0.6372 m2/g). Infrared and EDX studies confirmed modification of prepared material. The batch study was carried out by using 0.06 g/L of adsorbent dose at pH 7 for 120 minutes of contact time. The Langmuir qmax for PPE and DPE were observed to be 76.92 and 90.90 mg/g respectively.

“…Most of the contaminants adding up to wastewater are toxic and on the accumulation in living organisms possess a risk to them (Ambat et al 2020;Ben Hamida et al 2018;Bessaies et al 2020;Iftekhar et al 2020a, b;Wang et al 2019) For the depletion of these contaminants including heavy metal ions, dyes, organic contaminants, etc., a variety of methods have been employed along with various types of materials spanning from natural to synthetic, waste to hybrids and renewable to engineered (Hosseini et al 2019;Zare et al 2018b;Asif et al 2016;Gao et al 2017;Iftekhar et al 2017aIftekhar et al , 2018b. In recent decades, the paradigm has shifted toward the application of nanomaterials from bulk, causing the huge progressions of nanotechnology in creating novel nanomaterials for many industrial and environmental applications.…”

The inert nature of most commercial polymers and nanomaterials results in limitations of applications in various industrial fields. This can be solved by surface modifications to improve physicochemical and biological properties, such as adhesion, printability, wetting and biocompatibility. Polymer functionalization allows to graft specific moieties and conjugate molecules that improve material performances. In the last decades, several approaches have been designed in the industry and academia to graft functional groups on surfaces. Here, we review surface decoration of polymers and nanomaterials, with focus on major industrial applications in the medical field, textile industry, water treatment and food packaging. We discuss the advantages and challenges of polymer functionalization. More knowledge is needed on the biology behind cell–polymer interactions, nanosafety and manufacturing at the industrial scale.
