Show Detailed Complexation Query Results

Surface Complex Formation Data:

Mineral:	amorphous Silica
Reference:	ZACS90
SCM Type:	TL - Triple Layer
Ligand:	AN<0> - aminonaphthalene
Site Type:	»Si-OH
Equation:	»Si-OH + AN<0> + H<1+> ⇔ »Si-OH2-AN<1+>
LogK:	4.25 LogK°_I=0 (Conversion to I = 0): 4.29
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 aminonaphtalene sorption -> reflects the heterogeneity of the surface?; log K = 4.25 for 1E-6 M aminonaphtalene and 4.06 for 1E-5M aminonaphtalene
