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.

Composite zeolite/carbonized polyaniline electrodes for p–nitrophenol sensing

Journal of Electroanalytical Chemistry, 2016
Abstract Electrodes based on composites of zeolites with carbonized polyaniline prepared in the presence of 5–sulfosalicylic acid are evaluated for both qualitative and quantitative determination of phenols in aqueous solutions. Zeolites used included NaX and NaY, as well as their transition metal (Mn and Cu) cation–exchanged forms, and they were all

Sorption of p-nitrophenol by anion–cation modified palygorskite

Journal of Hazardous Materials, 2009
A series of anion-cation modified palygorskites were prepared by microwave irradiation, and characterized with FT-IR. Compared with natural palygorskite, the p-nitrophenol sorption capacity with anion-cation modified palygorskite was significantly improved. The maximum sorption capacity (137.74 mg g(-1)) was obtained with the mass ratio 1:4 and 3:10 of

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.

Microwave assisted wet oxidation of p-nitrophenol

Science in China Series E, 2005
Aqueous solution of p-nitrophenol (PNP) was treated continuously by microwave assisted wet oxidation while flowing through a granular activated carbon (GAC) fixed bed. PNP was pre-adsorbed onto GAC prior to being put into the reactor so as to prevent PNP adsorption on GAC during microwave irradiation. PNP solutions with different initial concentration (
