Description:
Studies were conducted to evaluate lipophilicity as a predictor of sorption for a mixture of organic compounds with high vapor pressures commonly present at hazardous waste sites. orption partition coefficients (Kp) for the mixture of 16 volatile and semivolatile organic compounds were measured on a Captina silt loam (Typic Fragiudult) and a McLaurin-sandy loam (Typic Paleudults) using a zero headspace extractor. he experimental Kp was determined f or acrylonitrile, furan, methyl ethyl ketone, tetrahydrofuran, benzene, toluene, p-xylene, chlorobenzene, chloroform, nitrobenzene, 1,2-dichlorobenzene, 1,2,3-trichloropropane, carbon tetrachloride, ethylene dibromide, 1,2,4,5tetrachlorobenzene, and hexachlorobenzene on each of the two soils. he K p values were generally lower in the McLaurin sandy loam, which had a lower organic C content (0.66 +/0.04%) than the Captina silt loam (organic C content = 1.49 +/- 0.06%). Sorption was normalized to soil organic c content of the soil by converting K p for each compound and soil to Koc.
