The influence of module arrangements on solvent extraction of thallium(III) from NaCl/H 2 SO 4 solution into butyl acetate has been studied using two laboratory‐made modules consisting of hydrophobic polypropylene hollow fibers. The aqueous phase was recirculated between the module(s) and a mixed reservoir, and the organic phase was stagnant on the shell side. It was found that the extraction of Tl(III) from aqueous phase strictly depends on aqueous flow rate and module arrangement. The results obtained are discussed in terms of the fraction of Tl(III) removed from the aqueous phase reservoir, the flux of Tl(III) through the interfacial area, and the best arrangement of modules for the production process of the radiopharmaceutical 201 TlCl.
