RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results

Surface Complex Formation Data:

Mineral:	Bentonite
Reference:	MG07
SCM Type:	NE - Non-electrostatic
Ligand:	Ca<2+> - calcium
Site Type:	»X(w)-OH
Equation:	»X(w)-OH + Ca<2+> ⇔ »X(w)-O-Ca<1+> + H<1+>
LogK:	-4.4
Experiment:	Sorption Isotherms
Ionic Strength:	NaClO4
Temperature:	298.15 K
pH Range:	6.5
Ligand Concentration Range:	1E-9 - 1E-4 mol/L
Fit Method:	CHESS
Comment:	S/L ratio = 1-6 g/L; ion exchange 2»XNa + Ca<2+> = (»X)2Ca + 2Na<1+> with logK = 0.65; obviously wrong equation in the article: »X(w)-OH + Ca<2+> = »X(w)-OH-Ca<1+> + H<1+>
