Abstract
Adsorption of halogen ions onto the anion ion-exchange resin, Dowex 2-X 8, and ratedetermining steps of the ion exchange reaction were studied by means of the batch method in the presence of magnetic field. Halogen ions used were F-, Cl-, Br- and I- ions. The magnetic flux density was O.25 T. Ion-exchange rates of all ions were increased by about 10-20% by the presence of the magnetic field. Magnetic field does not affect on the degre e of swelling, the structure of the resin, viscosities and electric conductivities of sample solutions, and total ion exchange capacities. It was found that the rate-determining step of all ionexchanges is the film diffusion and particle diffusion. Its diffusion coefficients and rate constants are increased by the pressence of the magnetic field.
