Surface Complex Formation Data:

Mineral:	Quartz
Reference:	S06c
SCM Type:	TL - Triple Layer
Ligand:	NO3<1-> - nitrate
Site Type:	»Si-OH
Equation:	»SiOH + NO3<1-> + H<1+> ⇔ »SiOH2<1+>NO3<1->
LogK:	-0.2
Ionic Strength:	KNO3
Temperature:	298.15 K
Fit Method:	Unknown
Comment:	estimated based on the zpc and log()K°(M+) (see article); equilibrium constants in this study refer to site-occupancy standard state with hypothtical 1.0 M ionic strength (K°) and values for N' = 10 10^18 m^-2 and A' = 10 m²/g using the equation: K = K°(Ns * As/N' * A'), where Ns represents the SSD = 11.4 sites/nm² from [V76] and As the SSA = 4.2 m²/g from [V76]; parameters predicted from equations in [S05]; pH(ZPC): calculated assuming that K(»X-O<1->Ca(OH)<1+>), for [V76] is the same as that derived from the data of [R83]
