RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Kaolinite
Reference: WWD98
SCM Type: DDL - Diffuse Double Layer
Ligand: F<1-> - fluoride
Site Type: »Al-OH
Equation: »Al-OH + F<1-> + H<1+>  ⇔  »Al-F + H2O
LogK: 15.16        LogK°I=0 (Conversion to I = 0):   15.37         LogK2.31 nm−2 (SSD-normalized):   17.87
Experiment: Batch Sorption Experiments
Ionic Strength: 0.1 mol/L NaNO3
Fit Method: FITEQL
Comment: when F-concentration <1mM: only one reaction site (>>AlOH) was needed to model fluoride adsorption; conc. 0.001mM to 0.1mM: considering both >>AlF and >>SiF species
