Journal Article

The recovery of Zn(II) from chloride solutions using pseudo-emulsion based hollow fiber strip dispersion (PEHFSD) technique with pyridine reagents was investigated. The pyridineketoxime extractants were used as the carriers: 1-(3-pyridyl)undecan-1-one oxime and its quaternary salts 3-[1-(hydroxyimine)undecyl]-1-propylpyridinium bromide and 3-[1-(hydroxyimine)undecyl]-1-propylpyridinium chloride. The influence of several parameters, among them the hydrodynamic conditions, extractant, metal and strippant concentrations, as well as, the extractant structure on the zinc(II) extraction was studied. The surface properties of the various aqueous/organic systems and mass transfer resistances were also determined. The extractants proposed showed to be appropriate carriers in the PEHFSD process and the values of overall mass transfer coefficient of permeation were found in the range of 2.5 × 10−7–1.1 × 10−6 m/s. © 2016 Elsevier B.V.
