Comment: |
bidentate model; Common logarithms of the intrinsic surface complexation constants (log Kint values) ± standard deviation for Sb(V), PO4, and SO4 adsorption were optimized using FITEQL and suspension parameters described in Tables 1 and 2 and the ligand adsorption edge data presented in Fig. 3. |
