Task-specific Ionic liquids for the solvent extraction of Molybdenum (VI) from aqueous solutions
(2017)
Molybdenum, Mo(VI), is recovered from leach liquors of molybdenite concentrates
by mean of solvent extraction (SX) using bis(2-ethylhexyl)phosphoric acid
(D2EHPA) as the extractant and kerosene as the diluent. However, ...
Extraction of cadmium from aqueous solutions by emulsion liquid membranes using a stirred transfer cell contactor
(SOC BRASILEIRA QUIMICA, 2006-12)
It is studied the extraction of cadmium( II) ions from acidic aqueous solutions using a stirred transfer cell-type emulsion liquid membrane ( ELM) prepared by dissolving in kerosene, with D2EHPA ( an alkylphosphoric acid) ...
Recovery of copper from leaching residual solutions by means of a hollow-fiber membrane extractor
(Elsevier Ltd, 1996)
A process of recovery of copper from acid leach residual solution with 5-dodecylsalicylaldoxime dissolved in n-hexane was carried out at 30°C in a countercurrent tubular membrane extractor using a hollow fiber as solid ...
Optimizing Selection of Assessment Solutions for Completing Information Extraction Results
(Revista Computación y Sistemas; Vol. 17 No.2, 2013-06-07)
Abstract. Incomplete information produces serious consequences in information extraction: it increases costs and leads to problems in downstream processing. This work focuses on improving the completeness of extraction ...

Characterization of chemical kinetics in membrane-based liquid-liquid extraction of molybdenum(VI) from aqueous solutions
(2009)
This study aims to describe the mass transfer in a membrane-based solvent extraction system for the extraction of molybdenum(VI) from aqueous solutions, identifying chemical kinetics of the complex formation at the interface. ...
Fractionation and redox speciation of antimony in agricultural soils by hydride generation-atomic fluorescence spectrometry and stability of Sb(III) and Sb(V) during extraction with different extractant solutions
(AOAC INTERNATIONAL, 2004-01)
This stability of Sb(Ill) and Sb(V) species was studied during,single extraction from soils by water. EDTA, diluted H2SO4 and H3PO4, and oxalic acid/oxalate solutions, with and without ascorbic acid, were used as stabilizing ...
