Bioelectrochemical system for recalcitrant p-nitrophenol removal

Journal of Hazardous Materials, 2012
Bioelectrochemical system (BES) for recalcitrant p-nitrophenol (PNP) removal was investigated in this study. Effective removal of PNP at rates up to 9.14 ± 0.48 mol m(-3)d(-1) was achieved at an energy consumption as low as 0.010 ± 0.002 kWh mol(-1) PNP. PNP removal rate was enhanced with negative cathode potential, increased influent PNP concentration

Mineral-modulated Co catalyst with enhanced adsorption and dissociation of BH4- for hydrogenation of p-nitrophenol to p-aminophenol.

Chemosphere, 2021
Slow adsorption and dissociation kinetics of NaBH4 onto the catalyst surface limit the hydrogenation reduction of hazardous p-nitrophenol to worthy p-aminophenol. Herein, we design a mineral-modulated catalyst to facilitate the rate-limiting step. Carbon-

Biodegradation of p-nitrophenol by P. putida

Bioresource Technology, 2006
A strain of Pseudomonas putida was found capable of metabolizing p-nitrophenol (PNP) as a sole source of carbon, nitrogen and energy. To explore the applicability of this strain for bioremediation for controlling environmental PNP pollution, its degradation potential at 300 and 500 ppm was examined in a medium devoid of carbon and nitrogen source ...

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.

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 ...
