Comment: |
40 °C; assumed that only the clay mineral, montmorillonite, contributes to Np sorption; logK(int): calculated by multiplying the stability constants of the corresponding aqueous complexes to Ks; 60 Bq/ml;FIT Method: GESPER (modified version of the CHEMTRN code); !! 2 SSA values measured (BET, EGME) --> not clear which one was used for modelling --> here BET SSA is linked with the modelling results |
