Determination of carbon-14-labeled 3,4-benzopyrene adsorbed on different solids
Recovery studies for 3,4-benzopyrene (BaP) are necessary for quantifying polynuclear aromatic hydrocarbons on solid matrices. One of the main problems in recovery studies is the simulation of samples, on which a known quantity of BaP is adsorbed and homogeneously divided on solid substrates. In this study the samples were spiked by the addition of a toluene solution containing /sup 14/C-BaP, taking into account that BaP was not homogeneously divided on the adsorbent. The samples were treated by two destruction methods, i.e., a wet destruction with a potassium dichromate-sulfuric acid and orthophosphoric acid and a combustion with oxygen. The liberated CO/sub 2/ was adsorbed and the /sup 14/C radioactivity analyzed by means of liquid scintillation counting. 6 references, 1 figure, 5 tables.
