Desalination and heavy metal ion removal from water by new ion exchange membrane modified by synthesized NiFe 2 O 4 /HAMPS nanocomposite KU Leuven
© 2019, Springer-Verlag GmbH Germany, part of Springer Nature. Magnetic nickel ferrite (NiFe 2 O 4 ) nanoparticles were synthesized and then modified by a novel hydrogel based on 2-acrylamido-2-methyl propane sulfonic acid (HAMPS). Field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) analyses were conducted to prove the NiFe 2 O 4 /HAMPS nanocomposite formation ...
Effect of anionic fluidized ion exchange (FIX) pre-treatment on nanofiltration (NF) membrane fouling Universiteit Gent
Mussel-inspired modification of ion exchange membrane for monovalent separation KU Leuven
© 2018 Elsevier B.V. Electrodialysis (ED) is a promising and widely used technique for producing drinking water. Nevertheless, the presence of multivalent ions like Mg2+ and Ca2+ can be challenging in practical applications, because this leads to precipitation in the concentrated compartment, thus decreasing the performance of the ED process. Monovalent ion exchange membranes are capable of separating monovalent ions from a solution containing ...
Making high salt concentrations for optimal chromatography compatible with electrospray ionization mass spectrometry using an ion exchange membrane suppressor: Analysis of biomarkers for transporter protein inhibition as a case study Vrije Universiteit Brussel
This study reports on the potential of using ion-exchange suppressor technology in liquid chromatography—electrospray ionization mass spectrometry workflows. The aim was to use high salt concentrations to improve separation performance, while overcoming the resulting significant ion suppression during electrospray ionization. As a case study, we apply suppressor technology to the hydrophilic interaction liquid chromatography separation and ...
Formulation and Characterization of Novel Hierarchical Ion Exchange Membranes for Electrodialysis Application KU Leuven
Electro-membrane processes are critical for implementing an effective water circular economy. Among them, electrodialysis (ED) is considered an effective alternative for brackish water desalination, wastewater treatment (in view of resource recovery), trace contaminants removal, and fractionation of metals (Li+, Mg2+, …). On an industrial level, the application of ED is still hindered by high investment and operating costs, to which ion exchange ...
Tailoring the electrochemical properties of ED ion exchange membranes based on the synergism of TiO2 nanoparticles-co-GO nanoplates KU Leuven
In this paper, the synergetic influence of various weight ratios of TiO2 nanoparticles (NPs)/graphene oxide nanoplates (GONs) in the matrix of ion exchange membranes was examined in order to adapt their electrokinetic properties based on the combination of the high specific surface area of GONs and the antifouling ability of TiO2 nanoparticles. The morphology, physico-chemical features and ionic transport behavior of prepared membranes was ...
Towards next generation high throughput ion exchange membranes for downstream bioprocessing: A review KU Leuven
Membrane chromatography is recognised as a potential solution to streamline downstream processing for protein purification, where ion exchange membrane chromatography (IEMC) as a polishing step to remove impurities has been successfully demonstrated in small scales. Despite limited commercial adoption in large-scale production, the concept of IEMC attracts many interests and tremendous progress is made. To fill the review gap for advancements in ...
Evaluating the ion transport characteristics of novel graphene oxide nanoplates entrapped mixed matrix cation exchange membranes in water deionization KU Leuven
© 2017 Elsevier B.V. Graphene oxide nanoplates (GONs) embedded mixed matrix polyvinylchloride based heterogeneous cation exchange membranes were prepared by solution casting. The effect of the concentration of GONs on the physico-chemical properties of the membrane was studied. Scanning electron microscopy (SEM) and scanning optical microscopy (SOM) images showed a uniform particle distribution and a uniform surface for the modified membranes. ...
Ion exchange membranes for vanadium redox flow battery (VRB) applications KU Leuven
The vanadium redox flow battery (VRB) has received wide attention due to its attractive features for large scale energy storage. The key material of a VRB is an ion exchange membrane (IEM) that prevents cross mixing of the positive and negative electrolytes, while still allowing the transport of ions to complete the circuit during the passage of current. This review focuses on all aspects related to IEMs that are of relevance to understand IEMs ...
