The formation of halogenated solvent artifacts was investigated in common analytical solvents exposed to free chlorine, chloramines, and free bromine. Three brominated solvent artifacts [3-bromo-3-methyl-2-butanol (BMB) ,l-bromc-2-methyl-2-propanol, and bromoacetone] were identified by gas chromatography/mass spectrometry in methyl tert-butyl ether or pentane exposed to free bromine. These same...

A series of photo-Fenton reactions have been performed for the degradation of 2,4,6-trinitrotoluene (TNT) in a 4.2-l reactor. The degradation reaction rate of TNT followed a pseudo-first-order behavior; and the rate constants for 2.4mW cm(-2)UV only, 2.4mW cm(-2)UV/H(2)O(2), Fenton, photo-Fenton (2.4mW cm(-2)) and photo-Fenton (4.7mW cm(-2)) were 0.002min(-1), 0.007min(-1), 0.014min(-1), 0.025m...

Though potentially useful, agricultural byproducts are often discarded because of the lack of specific applications in many industries. However, they have suitable properties for use in the paper industry, according to recent literature. In this study, the suitability of rice husk, peanut husk, and garlic stem as raw materials for the manufacture of a new lignocellulosic bulking agent was inves...

There is a significant potential to increase the sustainability of fishing and aquaculture industries through maximization processing byproducts. Enzymatic hydrolysis provides an opportunity valorize downstream fish industry byproducts for production protein hydrolysates (FPH) as source bioactive peptides (BAP) with health benefits. Deteriorative oxidative reactions may occur during enzymatic b...

sepals and petals are byproducts from saffron production process that waste without any use in iran. these byproducts containing a lot of anthocyanin and natural antioxidants.the aim of this study is determine efficiency of extraction and measurement of antioxidant activity and anthocyanin pigments of pollen and anther of saffron flower ,using mixed solvent of ethanol and hydrochloridic acid 1....

We construct biharmonic real hypersurfaces and Lagrangian submanifolds of Clifford torus type in CPn via the Hopf fibration; and get new examples of biharmonic submanifolds in S as byproducts .
