Název v původním jazyce

Comparison of perchloroethylene extraction techniques in soil gas survey quantification.

Popis výsledku v původním jazyce

This study compares static headspace technique and methanol extraction/purge-and-trap analysis followed by thermal desorption/gas chromatography in attempts for quantification of gas survey results in the determination of these chemicals in soil. Severalsoils were contaminated with aqueous solution of perchloroethylene (PCE) (140 mg L-1) using a vapor treatment method. Soil spiking took place up to 24 h in desiccator by exposing individual soil samples contained in open 40 mL glass vials to PCE evaporated from the solution. After exposure the samples were stored and analyzed within 2 days. The achieved results strongly suggest that gas extraction can provide quantitative results, regarding PCE concentration in soils, which are not significantly different from liquid based extraction analysis.
