“…Meanwhile, recent researches have focused on the use of nanoparticles (NPs) for water treatment owing to their adsorption efficiency and potent catalytic activities 12 , 13 . Much attention has been given to the use of magnetic NPs and the composites for water treatment when compared to other NPs, attributed to the easy of recovery of magnetic NPs from solution by magnetic attraction 14 , 15 . However, the problem encountered in the recovery of other NPs from the treated water due to their small sizes has limited their application.…”

Despite the efficiency of ZnO nanoparticle (NPs) composite adsorbents in the adsorption of various pollutants, there is presently no report on the combo of Znonps with biomass for adsorption. Besides, there is a dearth of information on the biosorption of celestine blue (ceB), a dye used in the nuclear and textile industry. in this study, biogenic-chemically mediated synthesis of a composite (Zno@Acp) was prepared by the impregnation of Znonps onto Ananas comosus waste (Acp) for the adsorption of ceB. the SeM, eDX, ftiR, XRD, Bet, and tGA characterizations showed the successful presence of Znonps on the biomass to form a nanocomposite. the uptake of ceB was enhanced by the incorporation of ZnONPs on ACP. A faster CEB adsorption onto ZnO@ACP (120 min) compared to ACP (160 min) was observed. The Langmuir (R 2 > 0.9898) and pseudo-second-order (R 2 > 0.9518) models were most appropriate in the description of the adsorption process. the impregnation of Znonps onto the biomass enhanced the spontaneity of the process and displayed endothermic characteristics. High CEB desorption of 81.3% from the dye loaded ZnO@ACP as well as efficient reusability showed the efficacy of the prepared nanocomposite for CEB adsorption. The pollution of environmental water from industrial effluents contaminated with industrial by-products is on the rise. This is attributed to the rapid growth of industries, hence the increase in industrial activities across the globe. About 700,000 tons of over 100,000 commercial dyes are produced annually in industries, which makes dye the most common water pollutant 1. Most dyes are used in the textile and paper industries and are frequently encountered in the effluents subsequently released into the environment 2,3. These dyes present in the environmental waters can be carcinogenic, mutagenic, and result in chronic illnesses in humans and aquatic organisms 3,4. Apart from that, they reflect or absorb light entering the water thus hindering the photosynthetic activity of aquatic plants 1. Therefore, the removal of dyes from wastewater is necessary to abate their harmful effects on the ecosystem 5,6. Most dye removal studies have focused on the removal of dyes such as methylene blue, congo red, malachite green, rhodamine B, methyl orange, methyl violet, reactive black, basic blue, acid yellow, brilliant green, and crystal violet 7,8. However, research on the removal of celestine blue (CEB) is rare despite the wide use of CEB in the nuclear and textile industries. Therefore, the removal of CEB from wastewater is important. Several techniques have been harnessed for the remediation of dye-polluted water, such as filtration, coagulation, oxidation, precipitation, reduction, photocatalytic degradation, solvent extraction, and adsorption 9. The adsorption technique is the most efficient and adsorption on bio-waste (biosorption) is promising due to the simplicity, low cost, degradability, reusability, and efficiency 10. Hence, the use of several bio-waste for the biosorption of dyes has received much attention,...

“…Almost all adsorption kinetics are better matched with the pseudo-second-order model, as evidenced by the better correlation coefficients compared to the pseudo-rst-order model. 89,90,93 In a study by Peng et al, 85 the adsorption data of ZIF-8-PAN NF for Cu(II) were adapted to a pseudo-second-order model (R 2 ¼ 0.967). The agreement of the kinetic data with this kinetic model suggests that the adsorption of HMIs on MOFs in aqueous solutions can be controlled by chemical adsorption.…”

“…The enrichment capacity of this MOF composite was 190 mg/g for both Cd 2+ and Pb 2+ ions and therefore completed the quantitative analysis with the detection limit of 0.2 and 1.1 μg/L and the relative standard deviations of less than 4.5%. Other functionalized groups and layers such as 4-(thiazolylazo) resorcinol, [242] ethylenediamine, [243] thiol, [244] thiadiazole, [245] benzoyl isothiocyanate, [246] L-cysteine, [247] dipyridylamine, [248] bisquinoline Mannich, [249] 1,5-diph-enylcarbazide, [250] carboxymethylcellulose, [251] cellulose na-nocrystal, [252] polydopamine, [253] urea, [254] chitosan, [255] mon-tmorillonite, [256] and even eggshell membrane [257] were also employed to conjugate with MOFs to develop functionalized MOF composites for heavy metal ion determination and removal in water, baby food, vegetable, sea food, etc.…”

Investigation on food safety and preservation is essential to provide high quality and safe food for human beings, including accurate determination and efficient removal of inorganic heavy metal ions and organic contaminants, as well as regulation of food postharvest ripening and intelligent sterilization. In the last two decades, metal-organic frameworks (MOFs), as functionalized porous materials, have aroused interests of researchers because of their advantages of high porosity, large specific surface area, flexible structure properties, and abundant binding sites for guest molecules. MOFs have shown great potentials in practical applications in food and related fields. In this overview, we summarized the MOF crystallization mechanisms, synthesis routes and methods, stability, as well as the applications in food contamination including removal of heavy metal ions, dyes, and antibiotics, and food preservation including regulation of fruit and vegetable ripening, removal of moisture and oxygen, and high-efficiency sterilization. Finally, two perspectives focusing on the development of MOFs for innovative food research, i.e., food-grade MOFs and MOF composites are suggested based on our understanding.
