| Abstract:: |
| Objective To study the effect of humic acid (HA) and soil on dissolution performance of depleted uranium (DU). Methods Using the static dissolve-adsorption experiment and inductively coupled plasma-mass spectrometry(ICP-MS) to determine uranium concentration and 235U/238U isotope ratios of the samples at different time and study the dissolution of DU in water. Results The solubility of DU in water was reduced by 90% by adding HA. Soil could increase the solubility of DU in water by nearly 25%, adding an appropriate amount of HA could play a supporting role on the dissolution of DU, in this experiment adding 5% of HA was best. Conclusions Soil and HA could produce positive and negative impact on the solubility of DU in water, and the combined effect of the two relied on the complex absorption and complexation reactions of soil, HA and dissolved uranium ions. |
