gamma-Ray destruction of PCBs on isooctane and transformer oil

Article Abstract:

Polychlorinated biphenyls (PCBs) are ubiquitous compounds that have been the target of a variety of degradation methods. A method that is showing potential is PCB radiolytic degradation in a nonpolar solvent. Studies investigating this technology in air-equilibrated isooctane and transformer oil reveal a significant degradation of PCBs in both solvents. Scavenging studies show that the electron is the primary reactive species responsible for PCB degradation thru this method.

Thermal reaction kinetics and mechanism of PCDF, PCDD, and PCB parent compounds and activated carbon on silica

Article Abstract:

Polychlorinated dibenzo-p-dioxins (PCDD), dibenzofurans (PCDF) and biphenyls (PCB) are environmental pollutants that have been the subject of several biological degradation studies. One approach to understanding the reactivity and toxicity of PCDD, PCDF and PCB is to investigate the thermal behavior of their parent compounds through the amount of activated carbon in air, with total organic carbon as a parameter. Experiments using this approach are presented.

Dioxin, Dioxins, Dibenzofurans

Degradation of octachlorodibenzofuran and octochlorodibenzo-p-dioxin spiked on fly ash: kinetics and mechanism

Article Abstract:

The importance of dechlorination and decomposition as reaction pathways is investigated. The degradation mechanisms for octachlorodibenzofuran and octachlorodibenzo-p-dioxin are also studied. The results showed that the two reaction pathways operated independently of each other because of a chemically-induced partition of reagents in the fly ash. The decomposition reaction was observed to be of the first-order.
