reduced adsorption
Of component \(i\), defined by the equation \[\mathit{\Gamma}_{i}^{(n)} = \mathit{\Gamma}_{i}^{\unicode[Times]{x3C3} }- \mathit{\Gamma}_{i}\ \frac{c_{i}^{\unicode[Times]{x3B1} } - c_{i}^{\unicode[Times]{x3B2} }}{c^{\unicode[Times]{x3B1} }- c^{\unicode[Times]{x3B2} }}\] where \(\mathit{\Gamma }^{\unicode[Times]{x3C3} }\), \(c^{\unicode[Times]{x3B1} }\) and \(c^{\unicode[Times]{x3B2}}\) are, respectively, the total @G02635@ concentration and the total concentrations in the bulk phases α and β: \[\mathit{\Gamma}^{\unicode[Times]{x3C3} }=\sum _{\begin{array}{c} i \end{array}}\mathit{\Gamma }_{i}^{\unicode[Times]{x3C3} }\] \[c^{\unicode[Times]{x3B1} }=\sum _{\begin{array}{c} i \end{array}}c_{i}^{\unicode[Times]{x3B1} }\] \[c^{\unicode[Times]{x3B2} }=\sum _{\begin{array}{c} i \end{array}}c_{i}^{\unicode[Times]{x3B2}}\] The reduced adsorption is invariant to the location of the @G02635@. Alternatively, the reduced adsorption may be regarded as the @G02635@ concentration of \(i\) when the @G02635@ is chosen so that \(\mathit{\Gamma }^{\unicode[Times]{x3C3} }\) is zero, i.e. the @G02635@ is chosen so that the reference system has not only the same volume, but also contains the same total @A00297@(\(n\)) as the real system.
