Dual removal and selective recovery of phosphate and an organophosphorus pesticide from water by a Zr-based metal-organic framework

Metal–Organic Frameworks as Potential Agents for Extraction and Delivery of Pesticides and Agrochemicals

“…Fenamiphos, another organophosphate with the structure shown in Table , was extracted using NU-1000 . In this study, simultaneous adsorption of fenamiphos and phosphate from water was studied.…”

“…82 Fenamiphos, another organophosphate with the structure shown in Table 2, was extracted using NU-1000. 111 In this study, simultaneous adsorption of fenamiphos and phosphate from water was studied. Optimum adsorption capacity for the pesticide is very high, 6400 mg g −1 , reaching equilibrium in 120 min.…”

A Ce-MOF as an alkaline phosphatase mimic: Ce-OH2 sites in catalytic dephosphorylation

“…Phosphatases are a class of hydrolytic enzymes composed of bivalent Zn(II) ions that are linked by a hydroxide bridge in their active sites and catalyze the hydrolysis of the phosphate ester (P-O) bonds of mono-, di-, and tri-esters, fluorophosphate, fluorophosphonate, phosphoric anhydrides, and many other similar enzymes. [1][2][3][4][5][6][7][8] These enzymes not only play an active role in the hydrolysis of organophosphorus compounds in several biochemical processes, such as DNA fragmentation, 9,10 RNA replication, and bone metabolism, 11 in agriculture (removal of phosphate-containing pesticides) 12,13 and in nerve agents 14,15 but also selectively govern the phosphorylation of biomolecules in vivo and abnormal hyperpho-sphorylation, which is strongly linked to Alzheimer's disease, lung cancer, and other human diseases. [16][17][18] Alkaline phosphatase (Scheme 1a) from E. coli (ALP, EC 3.1.3.1), particularly the mammalian enzyme, aids in the hydrolysis of phosphate ester (P-O) bonds and the release of inorganic phosphate in a basic environment.…”

Green synthesis of zirconium MOF-808 for simultaneous phosphate recovery and organophosphorus pesticide detoxification in wastewater

“…Only one very recent study, of our research group, reported the simultaneous capture and selective recovery of both P-pollutants by Zr-MOF NU-1000. 11 On the other hand, certain Zr-MOFs can hydrolytically degrade OPs in buffered media containing organic amines ( e.g. N -ethylmorpholine).…”
