The invention provides an ion separation device and an ion separation method formed by a magnetic field and ion exchange membranes. The ion separation device comprises the magnetic field, the anion exchange membranes, the cation exchange membranes, a main fluid flowing partition, a forward main fluid passage, a reverse main fluid passage and side concentrated solution passages, so that continuous separation of anions and cations can be achieved. The ion separation method includes: in the presence of the magnetic field, anions of flowing electrolyte solution pass through the anion exchange membranes while cations of the flowing electrolyte solution pass through the cation exchange membranes, cations of electrolyte solution in adjacent passages pass through the cation exchange membranes while anions of the electrolyte solution in the adjacent passages pass through the anion exchange membranes, and finally electrical property neutralization is respectively completed in high-concentration solution on two sides. The ion separation device and the ion separation method are applicable to seawater desalination and separation of solvend from solvent of the electrolyte solution, continuous operation can be achieved without regeneration and desorption, in-situ electrolyte solution ion separation is achieved, process is simple, ion separation efficiency is high, and fresh water recovery rate of aqueous electrolyte can be increased steplessly.
