Use of Kinetics for the Study of Exchange Reactions in Soils¹

ABSTRACT

Since exchange reactions are exceedingly rapid and soil phases must be separated for analysis, kinetic methods are difficult to use for their characterization. However, these methods can be used to identify the extent and contribution of exchange reactions to the retention of adsorbate ions. The difference between theoretical start concentration and the intercept of a log-normal plot of a kinetic reaction indicates the magnitude of the initial reaction(s), and a charge balance between ions lost from solution and exchange ions gained by solution will confirm whether the reaction is partly or entirely exchange. Using different initial concentrations, it is possible to construct isotherms for the exchange reaction.
