TLDR
In this paper, the degradation of methyl parathion (MP) adsorbed in metal-organic framework (MOF-199) cages was studied using solid-state 31P nuclear magnetic resonance (NMR), Raman spectrometry, and solvent extractions.Abstract:
Degradation of methyl parathion (MP) adsorbed in metal-organic framework (MOF-199) cages was studied using solid-state 31P nuclear magnetic resonance (NMR), Raman spectrometry, and solvent extractions. MP degradation was confirmed to be occurring when adsorbed in CuBTC MOF (MOF-199). Over 67 days of treatment, NMR results show that constitutional isomerization is an early mechanism of methyl parathion degradation with smaller amounts of oxidation (methyl paraoxon) and direct hydrolysis of MP followed by hydrolysis of these early degradation products. Raman spectrometry after 5 days and water extractions after 5 and 35 days supported this conclusion. 4-Nitrophenyl, a common MP degradation product, was observed with the amount increasing with exposure time or higher MP loading. Degradation of organic compounds such as methyl parathion, in addition to the selective physisorption, demonstrates the usefulness of MOF-199 for potential applications in protective materials and filtration.read more
