✦ Synopsis
We report observations ofa unique desorption phenomenon in ion exchange systems. Several experiments with the iodine laser system PERUN (A= 1.315 pm) were carried out in which laser-induced ion desorption from strongly acidic cation exchanger particles loaded by Na+ and Co'+ ions into water was satisfactorily proven. This effect is most probably caused by a laser-induced nonuniform temperature jump in the ion exchange system and by processes induced by corresponding temperature and pressure gradients. Under these conditions massive convective transfer of the intraparticle solution out of the ion exchanger particle is expected.
