ABSTRACT
The recovery of zinc(II) from model hydrochloric acid solutions in hollow fiber modules was studied. It was found that zinc(II) could be removed from these model solutions by 80% tributyl phosphate in kerosene. The efficiency of extraction was limited by low values of zinc(II) distribution coefficients. Two types of experiments were carried out: the extraction in one module and the extraction-stripping process in a set of two modules. Simplified models of mass transfer based on the solute concentration changes in the aqueous phases were formulated and verified.
