Non-dispersive extraction of ge(IV) from aqueous solutions by cyanex 923: Transport and modeling studies
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-11)
Article
Open AccessTransport process of germanium from an aqueous solution containing oxalic acid and 100 mg/L Ge was studied. Cyanex 923 immobilized in a polytetrafluoroethylene membrane was employed as a carrier in a flat-sheet supported ... -
Transient membrane potential after concentration step: A new method for advanced characterization of ion-exchange membranes
(2019-09-01)
Article
Restricted access - publisher's policyA better understanding of ion-transport mechanisms requires separate information on the equilibrium (partitioning) and kinetic (diffusivity) properties of the membranes with respect to ions. This work presents a novel ... -
Increasing sustainability on the metallurgical industry by integration of membrane nanofiltration processes: acid recovery
(2019-11-01)
Article
Restricted access - publisher's policyThe metallurgical industry generates large volumes of toxic effluents characterised, generally, by high acidity and a noticeable content of metals (Fe, Cu and Zn) and non-metals (As, Sb, Bi). The toxicity of these streams ... -
Selective separation of Germanium(IV) from simulated industrial leachates containing heavy metals by non-dispersive ionic extraction
(2019-06-15)
Article
Restricted access - publisher's policyGermanium can be found in industrial leachates of coal gasification fly ashes or zinc plant residues, containing various heavy metals. In this research, the selective separation of germanium from simulated water coal ... -
Improved rare earth elements recovery from fluorescent lamp wastes applying supported liquid membranes to the leaching solutions
(2019-10-01)
Article
Restricted access - publisher's policyDue to the continuously growing demand of rare earths in advanced technologies, end-of-life fluorescent lamps may become feasible rare earth elements (REEs) raw materials, reducing thus their supply risk. Considering acid ... -
Solvent extraction modeling of Ce/Eu/Y from chloride media using D2EHPA
(2019-05-03)
Article
Restricted access - publisher's policyEnd-of-life fluorescent lamps are becoming essential in the rare earths (REEs) field and suppose a feasible secondary source for getting them, reducing thus their supply risk. Considering the proved viability of the cationic ... -
Recent advances in smart integrated membrane assisted liquid extraction technology
(Elsevier, 2017-10)
Article
Restricted access - publisher's policyNovel processes based on SIMALE have been proposed as effective methods for the selective separation of different chemical species such as metal ions, organic/biologically important compounds and gas mixtures from different ... -
Fuzzy logic modeling of Pb (II) sorption onto mesoporous NiO/ZnCl2-Rosa Canina-L seeds activated carbon nanocomposite prepared by ultrasound-assisted co-precipitation technique
(2018-01-01)
Article
Open AccessIn this study, NiO/Rosa Canina-L seeds activated carbon nanocomposite (NiO/ACNC) was prepared by adding dropwise NaOH solution (2 mol/L) to raise the suspension pH to around 9 at room temperature under ultrasonic irradiation ... -
Bioactivity of glycolipopeptide cell-bound biosurfactants against skin pathogens
(2017-11-13)

Comparison of Cyanex 272 and Cyanex 572 for the separation of Neodymium froma Nd/Tb/Dy mixture by pertraction
(2017-09-29)
Article
Open AccessRecovering Nd(III) from wastemagnets is an alternative method to satisfy the increasing demand for this metal. For this reason, the separation of Nd from a mixture containing Nd/Tb/Dy in chloride media using Cyanex 272 and ... -
