Effect of Grain Size on Uranium(VI) Surface Complexation Kinetics and Adsorption Additivity Jianying Shang, Chongxuan Liu,* Zheming Wang, and John M. Zachara Pacific Northwest National Laboratory, Richland, Washington 99354, United States

bS Supporting Information ABSTRACT: The contribution of variable grain sizes to uranium adsorption/ desorption was studied using a sediment from the US DOE Hanford site. The sediment was wet sieved into four size fractions: coarse sand (12 mm), medium sand (0.21 mm), fine sand (0.0530.2 mm), and clay/silt fraction (
