Reference:	EPH13
SCM Type:	NE - Non-electrostatic
Ligand:	Th<4+> - thorium
Site Type:	»X(s)-OH
Equation:	»X(s)-OH + Th<4+> + 3 H2O ⇔ »X(s)-O-Th(OH)3 + 4 H<1+>
LogK:	-8.0
Experiment:	Batch Sorption Experiments

Comment:	Modeling was started from thorium surface reactions obtained from modeling kaolinite and applied to OLSR (saline ground water), parameters were reoptimized for illite; parameters and surface species of best fit from OLSR were applied to other waters (ALLMR, OLBA, OLGA)
