The parametric pump mechanism in separation of components in heterogeneous systems. I. Macroscopic distributed systems.

A dynamic method is proposed for the separation of the electrolyte components using a parametric pump with an ion exchange column. It was studied experimentally and described mathematically. The parametric separation of mixtures is based on interactions of two oscillating fields with a heterogeneous system containing two phases, a liquid and a solid one, the components of the mixture being able to redistribute between the phases. The field of mechanical force is responsible for cyclic relative displacement of the phases, and synchronously changing temperature causes redistribution of the components between them. This results in sodium and potassium fluxes opposite in direction which in turn leads to accumulation of sodium and potassium in opposite end cells.
