Abstract
The kinetics of solvent extraction of U(VI) with di(2-ethylhexyl) phosphori c acid (HDEHP) using a microporous hydrophobic hollow fiber membrane extrac tor has been investigated. The effects of U(VI) and hydrogen ion concentrat ions in aqueous phase, HDEHP concentration in organic phase, flow velocitie s of aqueous and organic phase and temperature on extraction rate of U(VI) were examined. The experimental results suggest that the extraction rate of U(VI) is controlled by diffusion.
