Binding Site Data:

Mineral:	Magnetite
Reference:	TS96
SCM Type:	CC - Constant Capacitance (C₁: 1.0 F/m²)
Ionic Strength:	0.1 mol/L of NaNO3
Site Type:	»Fe-OH
PZC:	6.7
pK1:	6.26	pK1°_I=0 (Conversion to I = 0):	6.15	pK1_{2.31 nm⁻²} (normalized):	6.26
pK2:	7.32	pK2°_I=0 (Conversion to I = 0):	7.21	pK2_{2.31 nm⁻²} (normalized):	7.32
Site Density in nm^-2:	2.3100
Original Site Density:	2.31 sites / nm² surface
Solid/Liquid Ratio in g/L:
pH Range:
Temperature in K:
Method for Site Density:	Literature
Method for Protolysis:	Best Estimate
Fit Method:	FITEQL
Comment:	uncertainty represents 95% confidence limit, experimental data from [RBM83], SSD from [DM90]; FITEQL did not converge at I=0.1M, extrapolated from log I vs. pK1 and pK2
