Photochemical degradation of azure-b with sulphate radical ion generated by peroxydisulphate ion with cupric ion

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

Organosilanes in Radical Chemistry

Radiation chemistry: Radical water.

I onizing radiation is known to be harmful to living organisms because it creates reactive radicals and charged species. In particular, highly energetic X-rays that ionize by removing one of the innermost (core) electrons of an atom lead to a cascade of events that must be better characterized if we are to fully understand their toxic effects 1. Writing in Nature Chemistry, Petr Slavíček, Bernd...

Free-radical chemistry of sulfite.

The free-radical chemistry of sulfite oxidation is reviewed. Chemical transformations of organic and biological molecules induced by sulfite oxidation are summarized. The kinetics of the free-radical oxidations of sulfite are discussed, as are the kinetics of the reactions of the sulfite-derived radicals SO3 and the peroxy derivative SO5 with organic compounds.
