Abstract: Isomorphic substitution, accompanied by surface adsorption, of a trace cation into a crystalline host matrix from its saturated solution can be studied by a double radiotracer experiment. Recrystallization of the matrix and uptake of the trace cation are thus measured simultaneously. This paper gives the formulation of the radiotracer experiment and the precision with which mole fractions of the trace cation in both phases, may be derived from it. The final result is thus a set of coexisting mole fractions and their uncertainties as a function of time. As an illustration, the case of calcite as the host matrix and CdII as the trace cation is considered. |
