The molecular disposition of p-nitrophenol and sodium p-nitrophenolate in the cyclohexaamylose cavity: A 13C probe

Bioorganic Chemistry, 1976
Abstract The direction in which both sodium p-nitrophenolate and p-nitrophenol penetrate the cyclohexaamylose cavity in aqueous solution has been examined by 13C-nmr. Both sodium p-nitrophenolate and p-nitrophenol penetrate the cavity asymetrically and quite specifically nitro group first with the phenolic oxanion or hydroxyl group pointing out into ...

Interaction of p-nitrophenol with lipids at hydrophobic interfaces

Langmuir, 1991
Adsorption of p-nitrophenol (PNP) at two model hydrophobic interfaces, namely at air/solution interface and mercury electrode/solution interface, as well as its interaction with neutral and charged lipids has been studied in monolayers by light reflection spectroscopy and electrochemical methods.

Experimental and theoretical investigations of a proton transfer supramolecular adduct, aminoguanidinium p-nitrophenolate: p-nitrophenol

Journal of Molecular Structure, 2019
Abstract Single crystals of aminoguanidinium p-nitrophenolate: p-nitrophenol (AGPNP) were grown by slow-evaporation method and the crystal structure of AGPNP was confirmed by Single crystal X-ray diffraction analysis. Spectral analyses such as FT-IR, 1H NMR and 13C NMR were carried out in order to detect the functional groups and find out the ...

p-Nitrophenol Biodegradation by Aerobic Microbial Granules

Applied Biochemistry and Biotechnology, 2012
Mixed microbial consortia in the form of aerobic microbial granules (AMG) capable of xenobiotic degradation can be developed from activated sludge or by adaptation of microbial granules pre-grown on labile carbon sources. Both of these approaches were investigated for the cultivation of AMG capable of p-nitrophenol (PNP) biodegradation.

Catalytic degradation of p-nitrophenol by magnetically recoverable Fe3O4 as a persulfate activator under microwave irradiation.

Chemosphere, 2020
In this study, Fe3O4 and microwave (MW) were combined to activate persulfate (PS) for the removal of organic matter, resulting in the enhanced degradation of p-nitrophenol (PNP) in solution.
