Intrinsic equilibrium constants triple layer model

Some triple layer model intrinsic equilibrium constants for surface complexation in the o-plane are Eqs. (6.10) to (6.13) as in the constant capacitance model, where h is replaced by 1, . Possible intrinsic equilibrium constants for surface complexation in the (3-plane are... 

Corresponding to these four conditional constants are the triple layer model intrinsic equilibrium constants ... 

Just as in the constant capacitance model, the intrinsic equilibrium constant in the triple layer model reters to an unconventional standard state wherein the complexed species create no coulombic effects, i.e., = K when (J4om = 0. 

Recently, the extended triple layer model (ETLM) was introduced by Sveijensky and coworkers (Sverjensky 2005 Sveijensky and Fukushi 2006), incorporating prediction of intrinsic equilibrium constants based on crystal chemical, electrostatic, and thermodynamic theory, allowing the reduction of adjustable parameters. In the ETLM, proton sorption Reactions 12.2 and 12.3 are written as associations ...
