Abstract  

Possibilities of the preconcentration of solutes in liquid-liquid extraction have been investigated from the point of view of transport processes in two models. It was found that the multistage dynamic (flow) column operation with a stationary extracting phase containing solutes to be separated enables to obtain higher preconcentrations than the one-stage static (batch) process with a factor available to reach its maximum value of 2 for separations approaching 100 percent extraction. The theoretical considerations were confirmed in the separation of131I from aqueous solutions.
