Abstract:The impact on the migration of depleted uranium in soils by humic acid and acid rain was studied using the improved DU migration model. The results showed that DU migrated to 9~11cm in control group(soils in beijing). In groups that 2%HA, 5%HA, 10%HA was added in soils, DU migrated further to 21~23cm,15~17cm,11~13cm, respectively, demonstrating that humic acid promoted the migration of depleted uranium. Leached by the simulated acid rain whose pH was 4.0and 3.0, DU migrated to 29~31cm and more than 35cm respectively, demonstrating that acid rain promoted the migration of depleted uranium. However,under the combined action of humic acid and acid rain, DU migratied to 5~7cm only, suggesting they restrained each other.
