T = 293.15-295.15 K, CO2-free solutions were used, which are stored under N2, logK fitted for zero ionic strength, experimented were done with 0.01 or 0.001 mol/L NaCl, Optimized values from FITEQL unless noted otherwise; the log Kint value for bidentate surface complex formation that is given in parentheses was computed according to Kint = rho*A*NS*KFITEQL, where rho is the solid/solution ratio (kg /L), A is the specific surface (m2 kg-1), NS is the site density (mol m-2), and KFITEQL is the K value optimized in FITEQL for bidentate surface complexes (TE02) logKFITEQL = 27.08 |
