Surface Complex Formation Data:

Mineral: Quartz
Reference: S06c
SCM Type: TL - Triple Layer
Ligand: Cl<1-> - chloride
Site Type: »Si-OH
Equation: »SiOH + Cl<1-> + H<1+>  ⇔  »SiOH2<1+>Cl<1->
LogK: -0.5
Ionic Strength: NaCl
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 = 4.5 sites/nm² from [R83] and As the SSA = 4.15 m²/g from [R83]; regression of surface charge data reported in [S05]; pH(ZPC): low ionic strength isoelectric point from [R83]
