RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

Show Detailed Complexation Query Results

Surface Complex Formation Data:

Mineral:	amorphous Silica
Reference:	ZACS90
SCM Type:	TL - Triple Layer
Ligand:	qui<0> - quinoline
Site Type:	»Si-OH
Equation:	»Si-OH + qui<0> + H<1+> ⇔ »Si-OH-(qui)H<1+>
LogK:	5.68 ± 0.14 LogK°_I=0 (Conversion to I = 0): 5.72
Experiment:	Batch Sorption Experiments
Ionic Strength:	0.01 mol/L NaCl
Temperature:	298.15 K
Solid/Liquid Ratio:	50.0 g/L
pH Range:	2.5-8.5
Ligand Concentration Range:	1E-6 mol/L
Fit Method:	FITEQL
Comment:	log K depends on initial quinoline sorption -> reflects the heterogeneity of the surface?; log K = 5.68 for 1E-6 M quinoline and 5.58 for 1E-5M quinoline
