An Improved Method for the Determination of Petroleum Hydrocarbons From Soil Using a Simple Ultrasonic Extraction and Fourier Transform Infrared Spectrophotometry

An environmentally friendly, cheap, and quick method for total petroleum hydrocarbons determination in solid matrixes (soil and sediments) is described. The method involves a simple extraction process (ultrasonic bath) and requires reduced amounts of solvent and solid sample. The analysis is carried...

Description
Summary:An environmentally friendly, cheap, and quick method for total petroleum hydrocarbons determination in solid matrixes (soil and sediments) is described. The method involves a simple extraction process (ultrasonic bath) and requires reduced amounts of solvent and solid sample. The analysis is carried out by Fourier transform infrared spectrophotometry. Detection limits were 63 or 24 mg kg −1 depending on the cell path length (10 or 40 mm, respectively). The method is suitable for application in weathered contaminated soils, which usually presents low availability of contaminants and seems to be a good choice, for instance, for monitoring evolution of soil or sediment recovering during a decontamination process.
