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;
original equation in the study: »Al-OH + NpO2(CO3)2<3-> + H<1+> = »Al-OH2-NpO2(CO3)2<2->, logK = 27.00 (NEA-TDB: NpO2<1+> + 2CO3<2-> = NpO2(CO3)2<3->, logK = 6.534) |
