Polychlorinated dibenzo-p-dioxins and dibenzofurans as products of photodegradation of chlorophenols

POLYCHLORINATED DIBENZO-p-DIOXINS AND DIBENZOFURANS AS PRODUCTS OF PHOTODEGRADATION OF CHLOROPHENOLS

Results of the study into photodegradation of 2,4,6-trichlorophenol and pentachlorophenol in aqueous solutions have been presented. Quantum yields and rate constants of the reactions were determined. Intermediate products were identified by GC/MS method. The experiments confirmed formation of polychlorinated dibenzo-p-dioxins and dibenzofurans in photochemical reactions. The findings showed tha...

Photodegradation of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans: direct photolysis and photocatalysis processes.

This study employed direct photolysis to treat mixed polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) solutions. The solutions included a synthetic standard 17 2, 3, 7, 8-substituted congeners solution and a practical liquid extracted from the bag filter ash of an electric arc furnace. Additionally, this work utilized a coupled catalyst (ZnO/SnO2) under UV irr...

Environmental toxicology of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans.

Few environmental compounds have generated as much interest and controversy within the scientific community and in the lay public as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Their ubiquitous presence in the environment and the risk of accidental exposure has raised concern over a possible threat of PCDDs or PCDFs to human health. The most extensively ...
