摘要: By using stirred-cell method as experimental technique, the kinetic transfer mechanism of UO22+ with N,N,N ' ,N ' -tetrabutyladipicamide (TBAA) from nitric acid solutions into toluene was studied. The different conditions effecting the extraction rate constants (k ' (f) and k ' (b)) were investigated, such as UO22+ concentration, HNO3 concentration, TBAA concentration, temperature and agitation speed. It was found that the extraction process was controlled by the diffusion of UO2(NO3)(2). 2TBAA from the liquid-liquid surface into the organic phase in the range of the experimental concentration of HNO3. The extraction rate was found to be of pseudo-first order with respect to the concentration of uranium(VI).
