Reference:	TLB95
SCM Type:	DDL - Diffuse Double Layer
Ionic Strength:	0.0 mol/L of
Site Type:	»Fe(s)-OH
PZC:
pK1:	7.29	pK1°_I=0 (Conversion to I = 0):	7.29	pK1_{2.31 nm⁻²} (normalized):	6.44
pK2:	8.93	pK2°_I=0 (Conversion to I = 0):	8.93	pK2_{2.31 nm⁻²} (normalized):	9.78
Site Density in nm^-2:	0.3276

Comment:	SSA, SSD (total) and pK from [DM90], other SSD was manually fitted; SSD(\"strong\" not in rhe sense of other site type!!!) corresponds to the value at which a plateau is observed in adsorption isotherms, indication surface site saturation
