The concentration of perfluorinated compounds (PFCs) contained in waste samples and eluted from the waste samples were measured respectively using sensitive method. The PFCs contained in the samples were extracted with methanol, while the PFCs were eluted with water. Afterward, the PFCs were separated, concentrated with nitrogen-gas and analyzed by LC/MS/MS. The results were considered focusing on the proportion and the difference in elution ratio of each PFCs.
As a result, it was confirmed that the concentration of PFCs contained in the samples can be measured without pulverizing solid waste. The differences in the concentrations contained in various kinds of waste samples were found depending on the category of industry, and treatment process. The elution ratio for the contained amount was different based on compounds. The short carbon chain compounds (C5-C8) had high elution rate, while long compounds (C9-C14) were low.
