Abstract:
The objectives of this study were to: (i) develop a mathematical model of the kinetics of an elementary cation-exchange and (ii) determine rate coefficients based on this model for K-Ca exchange on a vermiculite. The kinetics of exchange were described by a second-order mechanistic rate law from which the equilbrium exchange equation was derived. The second-order mechanistic rate law combined with an equation of mass balance describing transport were solved numerically. -from Authors
