Kinetic and dynamic study of liquid–liquid extraction of copper in a HFMC: Experimentation, modeling, and simulation

Abstract: In this work, we present the dispersion-free liquid-liquid extraction of copper from aqueous streams in a hollow fiber membrane contactor (HFMC). Copper has been transferred from aqueous solutions to heptane using LIX 84-I (2-hydroxy-5-nonylacetephenone oxime) as extracting agent. In a first step, batch experiments have been performed to identify the extraction kinetics and to measure the partition coefficient of copper aqueous-organic phase system. Then, the continuous recycled-base extraction process has bee… Show more

“…Aqueous solution of Cu 2+ is passed through shell of the module and the organic phase which was a mixture of 15 % v/v TFA in n-decanol was passed inside the fibers. As described in previous studies [5,27] such flow configuration results in higher extraction efficiency. Allowing the aqueous phase to flow in shell side of module increases the surface area as compared to inside fibers.…”

“…Both the modules studied here use membrane which is made of polypropylene. Although made of the same material, morphological and geometrical characteristics of membranes differ, for example X-40 membrane has a porosity of 0.25 and that of X-50 is 0.40 [5,27] and is enlisted in Table 1.…”
