Strontium Distribution Coefficients of Surficial and Sedimentary Interbed Samples from the Idaho National Engineering and Environmental Laboratory, Idaho

The transport and fate of waste constituents in geologic media is dependent on physical and chemical processes that govern the distribution of constituents between the solid, geologic, stationary phase and an aqueous, mobile phase. This distribution often is quantified, at thermodynamic equilibrium by an empirically determined parameter called the distribution coefficient (Kd). Kd's can be used effectively to summarize the chemical factors that affect transport efficiency of ground-water constituents. Strontium distribution coefficients (Kd's) were measured for 21 surficial and 17 sedimentary interbed samples collected from sediment cores from selected sites at the Idaho National Engineering and Environmental Laboratory (INEEL) to help assess the variability of strontium Kd's at the INEEL as part of an ongoing investigation of strontium chemical-transport properties. Batch experimental techniques were used to determine strontium Kd's of the sediments. Measured strontium Kd's of th e surficial and interbedded sediments ranged from 26{+-}1 to 328{+-}41 milliliters per gram. These results indicate significant variability in the strontium sorptive capacities of surficial and interbedded sediments at the INEEL. Some of this variability can be attributed to physical and chemical properties of the sediment; other variability may be due to compositional changes in the equilibrated solutions after being mixed with the sediment.
