Abstract:

Two- or three-component catalysts composed of (i) sulfur or sulfur compound (H2S, CS2, COS, Na2S), (ii) basic additive (triethylamine, CH3ONa, Na2S), and usually (iii) vanadium(V) compounds (e.g. NH4VO3) were found to catalyze efficiently the reaction of CO + H2O with isomeric nitrophenols to give the corresponding aminophenols. The reaction proceeds smoothly at 398 and 483 K and initial pressure of 7 MPa, and its rate increases from 2- to 4-nitrophenol. The selectivity to aminophenols exceeding 96 per cent was obtained at the water to nitrophenol molar ratio higher than 5. The solvents such a

The moderately halophilic anaerobic eubacteria Haloanaerobiumpraevalens and Sporohalobactermarismortui are able to reduce p-nitrophenol and a variety of other nitrosubstituted aromatic compounds at a high rate to the corresponding amines. p-Nitrophenol was not incorporated by the cells or degraded to acid-volatile compounds. Other compounds transformed included nitrobenzene, o-nitrophenol, m-nitrophenol, nitroanilines, 2,4-dinitrophenol, and 2,4-dinitroaniline. Also sheep rumen fluid was found to transform p-nitrophenol and a number of other nitroaromatic compounds at a high rate. At least 50%

Abstract:

An anaerobic biological fluidized bed was used to treat a synthetic wastewater containing three types of nitrophenols. The results proved that para-nitrophenol (p-NP) was the most toxic nitrophenol to methane producing bacteria while meta-nitrophenol (m-NP) was found to be less toxic, with ortho-nitrophenol (o-NP) being the least toxic to the methane bacteria. The results also showed that o-NP was much more easily decomposed by the microbes on the activated carbon biofilm. During the anaerobic digestion it was found that wastewater containing o-NP had the largest specific methane production ra

Abstract:

The low molecular-mass organic compound 4-nitrophenol is involved in many chemical processes and is commonly present in soils and in surface and ground waters, thereby causing severe environmental impact and health risk. Several methods have been proposed for its transformation (bio and chemical degradation). However, these strategies not only produce equally or more toxic aromatic species but also require harsh operating conditions and/or time-consuming treatments. In this context, we report a comprehensive and systematic study of the electrochemical reduction of 4-nitrophenol as a viable alt

ABSTRACT Ralstonia eutropha JMP134 utilizes 2-chloro-5-nitrophenol as a sole source of nitrogen, carbon, and energy. The initial steps for degradation of 2-chloro-5-nitrophenol are analogous to those of 3-nitrophenol degradation in R. eutropha JMP134. 2-Chloro-5-nitrophenol is initially reduced to 2-chloro-5-hydroxylaminophenol, which is subject to an enzymatic Bamberger rearrangement yielding 2-amino-5-chlorohydroquinone. The chlorine of 2-amino-5-chlorohydroquinone is removed by a reductive mechanism, and aminohydroquinone is formed. 2-Chloro-5-nitrophenol and 3-nitrophenol induce the expres

The results reveal an inverse correlation between the catalytic efficiency for BH4− hydrolysis and 4-nitrophenol reduction, indicating that catalysts performing well in one process exhibit lower activity in the other.

Abstract:

In this study, we developed an alternative of 4-nitrophenol reduction mediated by silver nanoparticles (AgNPs) which was synthesized using aqueous extract of the Peronema canescens leaf through an eco-friendly approach. The reducing 4-nitrophenol to 4-aminophenol mediated by AgNPS in the presence of sodium borohydride as a hydrogen source proceeded rapidly at room temperature without any additional treatments. The AgNPS synthesis was simple and was carried out under mild conditions. Ultraviolet–visible spectroscopy was performed to examine the properties of the obtained AgNPs, which displayed

Abstract:

Abstract The integration of liquid chromatography (LC) with immunochemical detection combines the superior separation power of LC and the sensitivity and specificity of immunoassays. This approach is shown with 3 LC systems (Perkin-Elmer, C18 RP, 4.6 mm; Varian, C18 RP, 1 mm microbore; Michrom, C18 RP, 1 mm microbore) Integrated with an enzyme-linked immunosorbent assay (ELISA) selective for five 4-nitrophenols. The nitrophenols were separated with the 3 LC systems with isocratic runs of 15 to 20 min. Microbore LC separation showed a 10-20 times reduction in solvent amount compared to conventi

Abstract:

Abstract In the present study, the green chemistry approach for the biosynthesis of Ag, Au and Ag-Au bimetallic nanoparticles (NPs) was applied using lichen extract [Cetraria islandica (L.) Ach.]. The lichen extract acts both as a reducing and stabilizing agent. The monometallic and bimetallic NPs were characterized by transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis) spectroscopy and Fourier transform infrared (FTIR) spectroscopy. The results showed that NPs were successfully synthesized and the prepared structures were generally spherical. The synthesized nanostructures ex

Abstract:

In this study, Cu20-polyoxotungstate [Cu20Cl(OH)24(H2O)12(P8W48O184)]25− supported on a magnetic substrate was used as a high-performance green method for the reduction of nitrophenol compounds such as 4-nitrophenol (4-NP) and 2,4,6-trinitrophenol (2,4,6-TNP). [Fe3O4@SiO2-NH2-Cu20P8W48] as heterogeneous magnetic nanocatalyst was synthesized and characterized by FT-IR, SEM, TEM, VSM, and TGA. This nanocatalyst has an excellent efficiency in the reduction of nitrophenol compounds to aminophenol compounds. The UV-Vis absorption spectrum is used at different times to evaluate the progress of the r

Abstract:

p-Aminophenol was prepared by electrocatalytic hydrogenation of p-nitrophenol using Ag + Fe + Fe3O4 (or Fe2O3) composites as catalysts formed during heat treatment and electrochemical reduction of silver ferrite, AgFeO2. AgFeO2 samples were synthesized by co-precipitation method without and in the presence of a polymer (polyvinyl alcohol, polyvinylpyrrolidone). The effect of the polymers on the phase constitutions of metal composites formed at the stage of synthesis, during the heat treatment and electrochemical reduction was established.
