摘要

Strontium-90 is one of the sizable radioactive contaminants found in DP Canyon at211u001eLos Alamos, New Mexico. Radioactive surveys found the (sup 90)Sr is present in 211u001esurface and groundwater in DP Canyon and Los Alamos Canyon. Colloids may 211u001einfluence the transport of this radionuclide in surface water and groundwater 211u001eenvironments in both canyons. In this study, we investigated the 211u001esorption/desorption behavior of Sr on colloids of smectite and silica. Laboratory 211u001ebatch sorption experiments were conducted using (sup 85)Sr as a surrogate to (sup 211u001e90)Sr. Groundwater, collected from DP Canyon and from Well 0-13 at Yucca 211u001eMountain, Nevada, and deionized water were used in this study. Our results show 211u001ethat 92% to 100% of (sup 85)Sr was rapidly adsorbed onto smectite colloids in all 211u001ethree waters. The concentrations of Ca(Sup 2+) significantly influence the 211u001eadsorption of (sup 85)Sr onto silica colloids. Desorption of (sup 85)Sr from 211u001esmectite colloids is much slower than the sorption process. Desorption of (sup 211u001e85)Sr from silica colloids was rapid in DP groundwater and slow using J-13 211u001egroundwater and deionized water.
