Abstract
A general numerical model is described for the dissolution kinetics of spherical particles in binary systems for any combination of first or der reactions at the particle-matrix interface and long distance diffu sion within the matrix. The model is applicable to both finite and inf inite media and handles both complete and partial particle dissolution . It is shown that interfacial reactions can have a strong effect on t he dissolution kinetics, the solute concentration at the particle-matr ix interface and the solute concentration profile in the matrix.
