|We introduce mathematical models for a shrinking-core process in a heterogeneous
reaction-diffusion system. The first model refers to diffusive mass transport. For this
case a novel numerical approach is presented, allowing for calculation of the moving
boundary as an explicit system variable. To cover the additional effect of migration
which is present in our experimental set-up, the model is modified to incorporate
electrical forces. Both models are compared and experimentally validated.||English|
