PARTITIONING OF ORGANIC AND INORGANIC COMPONENTS FROM MOTOR OIL INTO WATER

Partitioning of several volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs), and metals from new and used motor oil into water was investigated. Equilibrium distribution of these compounds between water and motor oil was measured using EPA Methods 624, 625, and 200 series. The intent was to establish chemical indicators to assist in identification of groundwater contamination from motor oil disposal/spill sources. Also, data from VOCs and PAHs was used to evaluate Raoult's law (ideal mixtures) behavior for oil-water distribution.
