Fig. 5. Measured, fitted and predicted breakthrough curves for the transport of B in columns G2, 3 (pH 6.9) and K2, 3 (pH 9.3) at pore water velocity u of 3.6 and 0.16 cm h–1, respectively, under pulse injection conditions (Tp = 0.8). Solid lines represent BTCs obtained by the fitting the LE-NE model to the experimental data (at u = 3.6 cm h–1) (
0 = 3.5 was obtained) and dashed lines represent predictions of the experimental data (at u = 0.16 cm h–1) by using the LE-NE model and 0 value of 39.
