The effects of nonlinear sorption on the diffusion of volatile organic compounds from air-dry soils: A theoretical study

An evaluation of in-situ bioremediation processes

“…The potential feasibility and effectiveness of an attached resting-cell filter strategy over extended periods of time has been demonstrated for degrading tirchloroethene flowing through a saturated homogeneous quartz sand (Oklahoma) by Taylor et al (1993), Shonnard et al(1994), , and Knapp et al(1995). This special method of allowing contaminants to flow through resting state microbial filters is, therefore, a great benefit in the technology.…”

Hazardous wastes: Assessment, management, minimization

“…Their model was based on the multicomponent form of the Brunauer-Emmett-Teller (BET) isotherm. The effects of nonlinear (BET) sorption on the rates of diffusion ofVOCs within and from contaminated air-dry soils were evaluated using a onedimensional gas-phase diffusion equation (Shonnard and Bell, 1994). They incorporated a dimensionless sorption parameter which accounted for the BET sorption phenomena on diffusive transport.…”
