Surface complexation constants for uranyl (UO 2 +2 ) sorption onto hydrous ferric oxide (HFO) using a diffuse layer model (DLM) developed with the Dzombak and Morel correlation are demonstrated to provide poor fits to two independently derived laboratory datasets. Alternative surface complexation reactions based upon geochemical modeling provided better matches to the data and still follow the underlying principles of the DLM as used in databases associated with several geochemical modeling programs.
