Description

An alternative current (A.C.) electric field was applied to disperse an aqueous phase of nitric acid solution in a solvent extraction system using tri-n-buthyl phosphate (TBP) diluted with n-dodecane. The diameter of the aqueous droplet dispersed through the A.C. electric field showed a log-normal distribution and an average diameter was 0.02 mm in 10% TBP. This average diameter is approximately 1/10 of the value obtained in the pulsed column which is currently used for nuclear fuel reprocessing. Through a batch-wise extraction experiment of U (VI), it was shown that extraction efficiency increases with frequency of the A.C. electric field. <BR>Through another experiment in continuous flow system, it was observed that the entrainment fraction of the aqueous phase into the product flow of an organic phase increases slightly with flow rate ratio, and yet it was found that it can be controled to be less than 0.2%. The experimental results indicate that application of the A.C. electric field is more suitable for lower TBP concentrations because of the increase of the electric conductivity of organic phase.
