Quantitative test for oils, crude oil, hydrocarbon, or other contaminants in soil and a kit for performing the same |
摘要 |
A method for the quantitative determination of oil in a soil matrix is provided, in which the method involves: extracting a soil sample with a solvent in the presence of a drying agent to provide an extract containing oil, if present in the soil sample, wherein the solvent is capable of complete solvation of oil and is completely miscible with water; filtering the extract; combining the filtered extract with water in the presence of an emulsifier to form an assay sample; and determining the amount of oil in the soil sample by measuring the turbidity of the assay sample to provide a turbidimetric response for the assay sample which correlates to concentration of oil present in the assay sample and comparing the turbidimetric response to a standard curve prepared from performing the methods on soil samples of known oil content. A kit for performing the method is also provided.
