Abstract

The paper aims at the analysis of principal factors affecting interaction of radiocobalt with freshwater solids, important for migration of radiocobalt in surface streams. Uptake and release of radiocobalt by sediment from a small river have been studied as a function of pH and composition of aqueous phase, the cobalt concentration and contact time, using laboratory model experiments. A factor of primary importance is the contact time due to slow and two-step kinetics of radiocobalt uptake, which also strongly depends on the concentration of sediment in suspension. pH exerts the most significant effect on the interaction in the pH region of 5–7.5, where the uptake increases with pH. Ionic strength of water phase (I) and concentration of cobalt in water (c) affect the interaction only at rather high values of I or c and their variation can be neglected in the modelling of radiocobalt transport in streams under ordinary conditions. Desorption by river water of radiocobalt pre-adsorbed on the sediment passes through a maximum with desorption time, decreases with increasing adsorption time and increases upon drying of the sediment prior to desorption. Results obtained are compared with literature data and conclusions are drawn concerning the mechanism of radiocobalt uptake by the sediment.
