“…This is due to the Donnan exclusion principle, which is attributed to the surface charge of -70 mV and the order of the hydrated metal radii. Besides these, one should also focus on the heterostructure composite of GO with other 2D materials including MXene, metal organic frameworks (MOFs), covalent organic frameworks (COFs), hexagonal boron nitride (h-BN), or transition metal dichalcogenides (TMDCs) to control the d-spacing for ionic and molecular sieving [112][113][114]. The recent work by Yin and co-workers has opened a new way to fabricate a high-separation-performance membrane based on GO and Mxene [115].…”

Graphene oxide (GO)‐based membranes have been widely investigated for separation of dyes, salt ions, heavy metal ions, and biomolecules due to their high mechanical strength, single‐layered structure, large surface area, and high affinity. However, due to irregular pore structure, nanochannels, interlayer distance, easy functionalization, swelling effect, and chemical stability under aqueous environment limited their separation efficiency. In this review, different fabrication methods of GO membranes are summarized. The role of functionalization and cross‐linking on membrane's structural properties, separation performance, and practical applications are discussed. Further, the GO‐based membranes (GOMs) for separation and removal of heavy metal ions are discussed in detail. The factors which influence the separation performance are also highlighted. Finally, recommendations and future directions are suggested.

“…However, the emergence of illegal additives such as melamine, Sudan dyes and plasticizer compounds has brought new threats to food safety [162,163]. In the analysis of illegal additives in foods, MMOFs materials with simple preparation and high adsorption efficiency are also used for food matrix purification and trace contaminants enrichment [164][165][166]. Lu et al have proposed a location-controlled strategy for functionalization of hydrophilic magnetic graphene by ZIF-8 MOFs to construct uniform and robust nanosheets (magG@PDA@ZIF-8) [167] (Figure 10a).…”

A variety of contaminants in food is an important aspect affecting food safety. Due to the presence of its trace amounts and the complexity of food matrix, it is very difficult to effectively separate and accurately detect them. The magnetic metal-organic framework (MMOF) composites with different structures and functions provide a new choice for the purification of food matrix and enrichment of trace targets, thus providing a new direction for the development of new technologies in food safety detection with high sensitivity and efficiency. The MOF materials composed of inorganic subunits and organic ligands have the advantages of regular pore structure, large specific surface area and good stability, which have been thoroughly studied in the pretreatment of complex food samples. MMOF materials combined different MOF materials with various magnetic nanoparticles, adding magnetic characteristics to the advantages of MOF materials, which are in terms of material selectivity, biocompatibility, easy operation and repeatability. Combined with solid phase extraction (SPE) technique, MMOF materials have been widely used in the food pretreatment. This article introduced the new preparation strategies of different MMOF materials, systematically summarizes their applications as SPE adsorbents in the pretreatment of food contaminants and analyzes and prospects their future application prospects and development directions.
