Fig. 3. Measured, predicted and fitted breakthrough curves for B adsorption and desorption on Columns (a) G1, (b) H, and (c) K1 at water flow rates u of 3.6 cm h^–1. Dashed lines represent predictions made by using the LE model and the batch-measured isotherm parameters (Table 1) and solid lines were obtained by fitting the LE–NE model to the experimental breakthrough curves (best fit values for f and ₀ are given in Tables 2).
