摘要：
The dynamics of multi-ion exchange is investigated with consideration for electric fields arising in sorbents when the ions with distinct diffusivities are exchanged. A new model for this process is developed. Simulation shows that the electric field can affect the dynamic break-through curves. The proposed model can be used for the creation of a new process of sorbents regeneration and microcomponents concentration.
