A NEW QUANTIFYING TOC AND COD METHODOLOGY FOR THE DETERMINATION OF ORGANIC-COMPOUNDS AND PARTICULATE CARBON DIRECTLY ON FLY-ASH OF MSWI

This paper presents a methodology for preparing a ''reagent'' sample t o study the formation reaction of PCDD/F from the carbon embedded on f ly ash without any modification in the structure of the raw fly ash. T he methodology combines Supercritical Fluid Extraction (SFE) of the or ganic compounds with Total Organic Carbon (TOC) and Chemical Oxygen De mand (COD) as control techniques.
