“…Due to the good hydrophilicity of LDH nanoparticles, solid-liquid separation needs to be performed by high-speed centrifugation or filtration (usually 0.45 µm membrane) after heavy metal ions are adsorbed in the research stage [128][129][130]. Yet, when absorbing heavy metal ions on a large scale, solid-liquid separation is costly and difficult to implement, which hinders the application of LDH.…”

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.

“…In recent years, magnetic solid-phase microextraction (MSPE) with magnetic materials as magnetic cores has been widely used in environmental science and food science because of its simple operation and high extraction efficiency [7]. In MSPE, pure magnetic materials, such as Fe 3 O 4 [8,9], CoFe 2 O 4 [10], and NiFe 2 O 4 [11], have poor acidic resistance and are prone to agglomeration. As a direct adsorbent, they will have poor adsorption efficiency for target analytes and low selectivity.…”

“…As a direct adsorbent, they will have poor adsorption efficiency for target analytes and low selectivity. Thus, the preparation of nanocomposites/nanohybrids is often adopted by using organic macromolecular carbon materials and/or ionic liquids to modify the pure magnetic materials [8][9][10][11]. Among them, carbon-based nanomaterials have advantageous physicochemical properties as the base or protective layer of pure magnetic materials, effectively avoiding the drawbacks of oxidation and agglomeration.…”

To simultaneously and efficiently extract pollutants with differential polarities, we herein fabricated and characterized a multifunctional nanocomposite. The novel nanohybrids used NiFe2O4 as magnetic cores, and NH2‐MIL‐101(Al), β‐cyclodextrin and graphene oxide as functional components combined with magnetic cores. With the aid of graphene oxide's large π‐conjugated system, NH2‐MIL‐101(Al)’s strong adsorption to moderately/strongly polar chemicals, and β‐cyclodextrin's specific recognition effect, the nanohybrids realized synergistically efficient extraction of polyaromatic hydrocarbons and bisphenols with a logKow range of 3–6. Combined with acidic and alkaline sources, the nanohybrids‐based effervescent tablets were prepared. Based on effervescent reaction‐enhanced nanohybrids‐based efficient adsorption/extraction and high performance liquid chromatography and fluorescence detection, we successfully developed an excellent microextraction method for the simultaneous determination of both polyaromatic hydrocarbons and bisphenols in roasted meat samples. Several important variables were optimized as follows: Na2CO3 and tartaric acid as acidic and alkaline sources, 900 μLof the mixed solvent (acetone and hexane at 2:1 by v/v) as the eluent, 5 min of elution time. Under optimized conditions, the novel method gave low limits of detection (0.07–0.30 μg kg−1), satisfactory recoveries (86.9–103.9%), and high precision (relative standard deviations of 1.9–6.7%) in roasted lamb, beef, pork, chicken, and sausage samples.
