Abstract

This paper presents a radiochemical study of the appearance of204T1I microcrystals and their development as “disks” resembling Liesegang rings, in gelatin, under different experimental conditions. Thus, kinetic diagrams have been traced, from which gel diffusion rate constants for radioactive ions were calculated, as well as reaction rate constants between reactant species:204T1+ and I−, in colloidal medium, followed by the development of concentrated microcrystals under form of one or more “disks”. There is an interconnection between gelatin concentration of the colloidal medium, on one hand, and204T1I microcrystal “disks” number and dimensions, on the other hand, “disks” which appeared in gel as a result of the global process of nucleation.
