Description

In order to understand the scavenging of radionuclides in paralic sediment, the adsorption of 85Sr (90Sr), 137Cs, 65Zn, and 60Co onto nearshore sediment was studied as a function of sediment grain size, salinity, temperature, and solid/liquid ratio. The adsorption kinetic data can be fitted well by pseudo-second-order kinetic model. Κd values for all four radionuclides decreased with the increase of grain size. Salinity and temperature have different influence on Κd values for 85Sr, 137Cs, 65Zn, and 60Co. With the increase of solid/liquid ratio, Κd value of 85Sr showed a linear decline, but Κd for 137Cs, 65Zn, and 60Co remained constant. Desorption of 85Sr was strongest in seawater, but 65Zn, 137Cs, and 60Co were strongly retained by marine sediments. (authors)
