As one aspect of the environmental chemistry of the actinide elements,the influences of inorganic ions,concentration of humic acid,pH value of the solution and temperature, etc. on reduction rate of Pu (Ⅵ) are studied. The results indicate that the reduction rate of Pu (Ⅵ) is proportional to the concentration of Pu (Ⅵ).
A multistage countercurrent extraction process is developed for the removaland recovery of actinides and lanthanides 30(V)% bidentate organophospho-rous extractant DHDECMP in diethyl benzene from mol/nitric acid solutionof simulated nuclear power reactor fuel reprocessing waste.
And a series of problems brought the change of the site of Lanthanide and Actinide site was put forward.
注 3: 锕充足比率可用于测量恒星的年龄。
Note 3: Actinide abundance ratios may be applied to measurements of stellar ages.
The inactive experiment of removing actinides from simulated HLLW by TRPO process is completed.
A flowsheet of TRPO process for removing actinides from high level waste solution is proposed.
