Fig. 4. Simulated dimethylphthalate (DMP) breakthrough curves at six different flow velocities using linear sorption rate parameters estimated for Oakville B soil. The quantification limit used to calculate recovery in Table 3 is also shown. The experimental conditions chosen for the three highest flow velocities are the same as those of the Exp. B1, B2, and B3 (figure modified after Selim et al., 1976)
