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.
