| Abstract:: |
| Objective To investigate the solubility characteristics of uranium oxide with different particle sizes,which was collected at site scene,in simulated lung fluid and other correlative buffer systems.Methods Uranium oxide particles were classified with a cascade impector.The percentage of cumulative soluble uranium with different particle sizes in simulated lung fluid and buffer solutions at different times were observed.Results Uranium oxides with smaller particle sizes had better solubility in simulated lung fluid and the solubility became higher with increase of time.The solubility of uranium oxide also became faster along with the increase of acidity of HAcNaAc buffer and increase of alkalinity of NH4OH-NH4Cl buffer systems.Uranium oxide was soluble in Na2CO3 solution and basically insoluble in NaH2PO4-Na2HPO4 solution.Conclusions Uranium oxides with smaller particle sizes have better solubility than bigger ones in simulated lung fluid.Uranium oxide is soluble in acidic HAcNaAc,alkaline NH4OH-NH4Cl buffer systems and Na2CO3 solution,but insoluble in NaH2PO4-Na2HPO4 solution. |
