Fig. 2. Plots of (top) lognormal distribution coefficient (lnK_d) vs. the inverse absolute temperature (1/T) for trichloroethylene sorption, and (bottom) lognormal sorption diffusion coefficient (lnD_s) and lognormal desorption diffusion coefficient (lnD_d) vs. 1/T for trichloroethylene sorption and desorption in soil humic acid at temperatures ranging from 15 to 35°C.
