Effect of dynamic competitive sorption on the transport of volatile organic chemicals through dry porous media



Effect of dynamic competitive sorption on the transport of volatile organic chemicals through dry porous media



Water Resources Research 35(5): 1347-1359



Dynamic (time-varying) competitive sorption, modulated through fluctuating relative humidity, significantly affected the diffusive flux of 1,2,4-trichlorobenzene through soil columns. The flux varied by a factor of up to 2 during a 24 hour cycle in the experimental system when subjected to humidity fluctuations of +or-40%. This effect was observed despite conditions in which sufficient water coverage would have been present to significantly depress volatile organic chemical (VOC sorption).
