Copper recovery from ammoniacal media using hollow fibre contactors
نویسندگان
چکیده
This work aims to study the recovery of copper from ammoniacal aqueous solutions using hydrophobic propylene membrane contactors. The hydroxyoxime LIX 84-I and the β-diketone LIX 54 (both from Cognis) were used as extractants. The results obtained showed that practically all the copper content was removed from the ammoniacal feed solutions. The recovery of copper reached nearly 100% in several extraction-stripping experiments. The results were compared with the ones obtained by applying the emulsion liquid membranes (ELM) technique.

Theoretical Studies on Copper Extraction by means of Polymeric Membrane Contactors
Solvent extraction of copper in hollow-fiber membrane contactors was investigated in this study. Extraction of copper is carried out conventionally using mixer-settlers. These contactors have some disadvantages such as consumption of high energy, dispersion of two phases and high operating costs. Membrane contactors can obviate the need for conventional contactors. The most favorable module use...

Miniature hollow fibre modules were fabricated as phase contactors for liquid-liquid extraction. They were tested for americium(III)-lanthanide separation, using 2,6-di(5,6-dipropyl-1,2,4-triazin3-yl)pyridine or a synergistic mixture of di(chlorophenyl)dithiophosphinic acid and tri-n-octyl phosphine oxide as extractants. Americium could be removed from the feed phase to 99.95% using the former ...

Separation of formic, acetic, and propionic acids from the aqueous stream using membrane solvent extraction has been studied using three different membrane contactors made of polysulfone (PS), polyethersulfone (PES), and polyvinylidene fluoride (PVDF) using two different solvents; including ethyl acetate (EA) and diisopropyl ether (DIPE). The efciency of the membrane and e...
متن کاملExtraction-Stripping Patterns during Co-Extraction of Copper and Nickel from Ammoniacal Solutions into Emulsion Liquid Membranes Using LIX 84I®
Extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (ELMs) was investigated using LIX 84I as the carrier. Measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the ELM extraction processes. The effect of operating parameters such as feed pH, initial feed concentration, and treat ...
