70 °C; estimated from sorption data onto goethite; 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;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 + HCO3<1-> + H<1+> = »Al-OH2-HCO3, logK = 24.4 (NEA-TDB: CO3<2-> + H<1+> => HCO3<1->, logK = 10.329) |
