Vanadium slag is an important resource containing valuable elements such as Fe, V, Ti, and so on. A novel selective chlorination method for extracting these from vanadium has been proposed recently. The methods could recover with a high recovery ratio less of environmental burden, while the study on mechanism at atom level was still insufficient. Fe2SiO4 FeV2O4 are two main phases slag, iron el...

Chloroperoxidase and horseradish peroxidase use NaClOz as both the oxidant and the halogen donor for the peroxidative chlorination of monochlorodimedone. Previous studies have shown that both horseradish peroxidase and chloroperoxidase can catalyze iodination reactions with hydrogen peroxide as the oxidant; however, only chloroperoxidase catalyzes chlorination reactions under these conditions. ...

N-acetyl-L-tyrosine (N-acTyr), with the alpha amine residue blocked by acetylation, can mimic the reactivity of exposed tyrosyl residues incorporated into polypeptides. In this study chlorination of N-acTyr residue at positions 3 and 5 in reactions with NaOCl, chloramines and the myeloperoxidase (MPO)-H2O2-Cl- chlorinating system were invesigated. The reaction of N-acTyr with HOCl/OCl- depends ...

Chlorination is a priority method for drinking water disinfection, since chlorine has strong bactericidal properties. However, whole set of volatile derivatives organic substances dangerous to humans are formed during chlorination, among which it necessary mention chloroform, carbon tetrachloride, chlorophenols. To reduce the concentration organochlorine derivatives, supplement current treatmen...
