Comment: |
Molar concentration based equilibrium constants, as input in MINEQL; SSD from [LBLS02], pk from [MD06] (The goethite database compiled by Mathur and Dzombak was based on the specific conditions of A = 60 m²/g and N = 2 sites/nm². The adaption of their constants in the present study was subject to corrections for site density and specific surface area.) |
