Kinetics and equilibrium partitioning of dissolved BTEX in PDMS and POM sheets

Abstract: Passive sampling of volatile organic chemicals from soil and groundwater is primarily important in assessing the status of environmental contamination. A group of low molecular weight pollutants usually found in petroleum fuels, benzene, toluene, ethylbenzene, and xylenes (BTEX) was studied for its kinetics and equilibrium partitioning with single-phase passive samplers using polydimethylsiloxane (PDMS) and polyoxymethylene (POM) as sorbing phase. PDMS (1 mm) and POM (0.076 mm) sheets were used for sorption of… Show more

“…These equilibrium-based passive samplers have been developed that are able to measure contaminant concentrations based on equilibrium partitioning . Such samplers are commonly made up of polymeric materials such as polydimethylsiloxane (PDMS) and polyoxymethylene (POM), whose VOC absorption properties have been previously investigated . However, kinetic-based passive samplers use materials with a high absorption capacity enclosed in an inert material such as a ceramic.…”

“…6 Such samplers are commonly made up of polymeric materials such as polydimethylsiloxane (PDMS) and polyoxymethylene (POM), whose VOC absorption properties have been previously investigated. 7 However, kinetic-based passive samplers use materials with a high absorption capacity enclosed in an inert material such as a ceramic. For these samplers, the concentrations are diffusion-based and cumulative over time, which enables the measurement of the time-integrated concentration.…”
