Abstract 4-Nitrophenol is a highly toxic environmental pollutant. It challenge to selectively remove it from mixture of various pollutants. Herein, we report study on the selective adsorption 4-nitrophenol by using molecularly imprinted polymers (MIPs). The polymer was synthesized cellulose as framework, onto which, complex imprinting molecule (i.e., 4-nitrophenol) and candidate material [namel...

The spectral characteristics of lactose repressor protein modified with two nitrophenol reporter groups have been determined. Reaction of Z-chloromercuri-4nitrophenol with repressor increases the apparent pK of the nitrophenol from 6.75 to 8.3 and alters the wavelength of maximum absorption. Subsequent binding of inducer shifts the apparent pK toward slightly more acid pH. The pK values of the ...

An ortho-nitrophenol solution was injected into the intestine which had been removed from an anesthetized mouse by placing a ligature at the duodenum and at the rectum. The intestine was then incubated in Ringer's solution at 37•Ž and the ortho-nitrophenol was found to be reduced to ortho aminophenol. At the same time, it was found that ortho-nitrophenol which was incubated with the intestinal ...

Rabbit liver UDP-glucuronyltransferase activity was resolved into two separate fractions on DEAE-cellulose, one containing most of the transferase activity toward oestrone and the other most of the activity toward p-nitrophenol. These two activities were completely separated by rechromatography of each fraction on a second DEAE-cellulose column.

We report the 4.04-Mb draft genome sequence of Arthrobacter sp. YC-RL1, an aromatic compound-degrading bacterium. YC-RL1 could degrade a wide range of aromatic compounds, including naphthaline, 1,2,3,4-tetrachlorobenzene, fluorene, 4-nitrophenol, bisphenol A, biphenyl, and p-xylene. The genome sequence of YC-RL1 will promote the investigation of the biodegradation of aromatic compounds.

Abstract It is challenging to develop a material which has low cost, high activity, good stability and recyclability under light exposure. Apart from these properties, the photocatalyst should also have visible region absorbance electron-hole pair recombination rate. Keeping all this in view, we designed simple scalable synthesis of ZnO–ZnS heterostructures for photocatalytic treatment industri...

In the present work, sol-gel synthesis method was employed as strategy to obtain a magnetic and mesoporous silica-niobia material. The planned based on heterocondensation of niobium silicon alkoxide precursors, in presence spherical magnetite particles. resulting material presented interesting characteristics such magnetism, large mesopores, range from 20 50 nm, 68 m2 g−1 surface area. These fe...

Bovine pancreatic deoxyribonuclease liberates p-nitrophenol from the 3'-group of deoxythymidine 3', 5'-di-p-nitrophenyl phosphate. A similar hydrolysis occurs with deoxythymidine 3'-p-nitrophenyl phosphate 5'-phsophate, but the rate is less than 2% of that with the di-p-nitrophenyl ester. The rate of formation of the p-nitrophenol, measured spectrophotometrically at 400 nm, varies linearly with...
