Hydrodynamic cavitation of p-nitrophenol: A theoretical and experimental insight

Chemical Engineering Journal, 2014
Abstract This paper presents a theoretical and experimental study of cavitation as an advanced oxidation process. The degradation rate of p-nitrophenol (PNP) was experimentally investigated and used as an estimator of the sonochemical effect in hydrodynamic cavitation. The PNP initial concentration was varied in the range 0.1–1 g L−1 and the pressure

Degradation of p-nitrophenol using a ferrous-tripolyphosphate complex in the presence of oxygen: The key role of superoxide radicals

, 2019
It has been recognized that a ferrous–polyphosphate complex can activate oxygen to produce reactive oxygen species (ROS) capable of degrading organic compounds. OH has been confirmed as the predominant ROS.

Determination of p-nitrophenol in human urine

Bulletin of Environmental Contamination and Toxicology, 1970
A rapid, sensitive gas chromatographic method for the determination of PNP in urine at levels as low as 50 ppb is described. The method involves an acid hydrolysis, cleanup, selective extraction, and on-column formation of the trimethylsilyl ether derivative of PNP.

Adsorption of p-nitrophenol on activated carbon fixed-bed

Water Research, 2006
Carbon fixed-beds are usually used to remove organic contaminants. Adsorption in a carbon filter is a dynamic, non-steady process which is not yet completely understood. The objective of this paper is to establish a methodology to simplify the study of this process based on the wave theory, rapid small-scale column test and experimental design/surface ...

Adsorption of p-Nitrophenol in Untreated and Treated Activated Carbon

Adsorption, 2004
The adsorption of p-nitrophenol in one untreated activated carbon (F100) and three treated activated carbons (H-2, H2SO4 and Urea treated F100) was carried out at undissociated and dissociated conditions. To characterize the carbon, N-2 and CO2 adsorption were used. X-ray Photoelectron Spectroscopy (XPS) was used to analyze the surface of the activated

Die Millon-Reaktion p-Nitrophenol

F�hner-Wielands Sammlung von Vergiftungsf�llen Archiv f�r Toxikologie, 1956
1. Es wird der Hinweis gegeben, das die Millon-Reaktion mit p-Nitrophenol zu einerQuecksilberkomplexsalzbildung fuhrt im Sinne der erstmaligen Beobachtung vonWhiteley, wobei die Nitrosierung von p-Nitrophenol in 2-Stellung durch eineQuecksilberkatalyse erzwungen wird, und eine Hypothese entwickelt, die geeigent erscheint, die Reaktionen vonMillon ...
