Bioderived pickering emulsion based on chitosan/trialkyl phosphine oxides applied to selective recovery of rare Earth elements
(2023-12-13)
Article
Accés obertA novel biobased pickering emulsion (PE) material was prepared by the encapsulation of Cyanex 923 (Cy923) into chitosan (CS) to selectively recover rare earth elements (REEs) from the aqueous phase. The preparation of PE ... -

Projecte/Treball Final de Carrera
Accés obertUn dels problemes a les indústries es presenta en la separació dels metalls, ja sigui per qüestiones econòmiques com per qüestions medioambientals. Aquest projecte es basa en un estudi on s’extreu cadmi amb l’extractant Cyanex ... -
Germanium transport across supported liquid membrane with Cyanex 923: Mathematical modeling
(2019-09-01)
Article
Accés obertA mathematical model was developed to monitor the facilitated transport of germanium(IV) from oxalic acid solutions through a flat sheet supported liquid membrane (FSSLM) containing four trialkylphosphine oxides (Cyanex ... -
Increasing the circularity of the copper metallurgical industry: Recovery of Sb(III) and Bi(III) from hydrochloric solutions by integration of solvating organophosphorous extractants and selective precipitation
(2023-02-01)
Article
Accés obertThe lack of high-purity ores has made the copper industry exploit low-impurity ores containing As, Sb and Bi which can affect the final product quality due to the floating insoluble arsenates. This is usually solved by ... -

(Elsevier, 2010-07-29)
Article
Accés restringit per política de l'editorialThis paper describes experimental work and the mathematical modeling of solvent extraction of cadmium( II) from neutral and acidic aqueous chloride media with a Cyanex 923 extractant in Exxol D-100. Solvent extraction ... -
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
Accés obertTransport 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 ... -
Permeability dependencies on the carrier concentration and membrane viscosity for Y(III) and Eu(III) transport by using liquid membranes
(2020-05-15)
Article
Accés obertThe recovery of Y(III) and Eu(III) from fluorescent lamp leachates via supported liquid membranes using Cyanex 923 as a carrier has been studied. The results reveal that the transport process is mainly controlled by the ... -
Recovery of germanium from leach solutions of fly ash using solvent extraction with various extractants
(Elsevier, 2018-01)
Article
Accés obertThe solvent extraction of germanium and some heavy metals by commercial tri-octyl/decyl amine (Alamine 336), N-methyl-N, N-dioctyl chloride (Aliquat 336) and phosphine oxide (Cyanex 923) has been studied. In each extraction ... -
Supported liquid membranes for the removal of pharmaceuticals from aqueous solutions
(2022-10)
Article
Accés obertIn the following study, the extraction of three pharmaceutical compounds: Diclofenac (DCF), ibuprofen (IBP), and carbamazepine (CBZ) by liquid-liquid extraction and their transport by supported liquid membrane (SLM) using ...
