Study of the transport process of uranyl ions in an ion-exchange membrane by solid-state track detector fissionography

A study was made of the diffusion of uranyl ions in an ion-exchange membrane of polystyrenesulphonic acid type. The solid-state track detector technique was used to prepare radiograms on the diffusion concentration profiles in the interior of the membrane at various diffusion times and temperatures....

Summary:A study was made of the diffusion of uranyl ions in an ion-exchange membrane of polystyrenesulphonic acid type. The solid-state track detector technique was used to prepare radiograms on the diffusion concentration profiles in the interior of the membrane at various diffusion times and temperatures. Fission fragments from 238U were detected in mica plates, and the local variations in the uranyl ion concentration were employed to determine the characteristic parameters of the transport process: the diffusion coefficients, the frequency factor and the activation energy.
