Fig. 6. The ratio effect of desorption rate coefficient to degradation rate coefficient on liquid-phase concentration over incubation time. C_eq is calculated using EB model with E_f value of one. C_d is calculated using Eq. [2] (overall mass balance equation with k_s value of zero) and Eq. [9] (first-order desorption-rate equation). The K_d value is assumed 3.3. R_sl is 0.1. and k_l is 0.006 min^-1.
