Quantitative comparison of de novo and precursor formation of polychlorinated dibenzo-p-dioxins under simulated municipal solid waste incinerator postcombustion conditions
Article Abstract:
University of Bayreuth researchers have identified two possible processes for the production of polychlorinated dibenzo-p-dioxin (PCDD) during municipal solid waste incineration: surface-catalyzed reactions of precursors, such as pentachlorophenol (PCP), and reactions from particulate carbon. Yields of PCDD from the first process were higher than yields from the second. Researchers concluded that carbon and Cu(II) represent two different types of catalysts present in fly ash. Experimental procedures and results are described.

Work area air monitoring for chlorinated dioxins and furans at a municipal waste power boiler facility
Article Abstract:
A large municipal waste incineration facility was the setting for a study that sought to measure concentrations of dioxins and dibenzofurans in effluents. Unlike previous investigations, which concentrated on toxic chemicals in fly ash, the Ohio study targeted dioxins and dibenzofurans in boiler room work areas. Experimental results found tetrachlorinated dibenzofurans and pentachlorinated dibenzo-p-dioxins in abundance. Researchers concluded that these concentrations were caused by combustion back-pressure or boiler leakage.

Sorption of organic contaminants by fly ash in a single solute system
Article Abstract:
Fly ash was applied as a sorbent material to remove organic contaminants from aqueous solutions. The waste product exhibited the ability for organic compound adsorption that is attributed to its carbon content. Positive correlation was also established between the Freundlich sorption capacity parameter and organic contaminant properties. The sorption process is channeled through the weak induction process of London or dispersion forces.
