Comparison of theoretical and measured phosphate-binding capacity of each coadministration at pH 2–8. The phosphate-binding capacity at (a) pH 2, (b) pH 3, (c) pH 4, (d) pH 5, (e) pH 6, (f) pH 7, and (g) pH 8. Each column shows the mean + standard error of three cases (two cases for CC and CC + FC at pH 2, ND for FC and CC + FC at pH 3, ND for FC and two case for CC + FC at pH 4, one case for FC and CC + FC at pH 5, one case for FC and CC + FC at pH 6, two cases for FC at pH 7, and two cases for FC at pH 8, as no adsorption was observed in any or all cases).
