Anthocyanin-rich extract from purple potatoes decreases postprandial glycemic response and affects inflammation markers in healthy men
(Elsevier, 2019-10-26)
Our recent clinical study suggested that polyphenol-rich purple potatoes lowered postprandial glycemia and insulinemia compared to yellow potatoes. Here, 17 healthy male volunteers consumed yellow potatoes with or without ...
Modeling the liquid-liquid extraction equilibrium of iron (III) with hydroxyoxime extractant and equilibrium-based simulation of counter-current copper extraction circuits
(Elsevier, 2018)
The phase equilibrium in the loading and stripping stages of the liquid–liquid extraction of iron (III) with hydroxyoxime extractant in kerosene was studied over a wide range of hydroxyoxime extractant (Acorga M5640, 3–25 ...
Ion exchange in complexing media – Nickel removal from ammoniacal ammonium sulfate solutions
(Elsevier, 2019-05-20)
In real hydrometallurgical systems, ion exchange of metal cations is often accompanied by competing processes, such as complex formation. In this paper, we have analyzed influence of complex formation on nickel uptake in ...
Experimental comparison of regeneration methods for CO2 concentration from air using amine-based adsorbent
(Elsevier, 2020-07-22)
Comparison of different regeneration options for direct air capture (DAC) has usually been limited to only consider pure CO2 production, limiting the process options to e.g. temperature-vacuum swing adsorption (TVSA) or ...
Recovery of lithium from leach solutions of battery waste using direct solvent extraction with TBP and FeCl3
(Elsevier, 2021-03-22)
Although societal interest in lithium has grown due to its increased demand for manufacturing of lithium ion batteries (LIBs), recent research studies about LIB recycling with solvent extraction did not focus on Li recovery ...
Removal of iron, aluminium, manganese and copper from leach solutions of lithium-ion battery waste using ion exchange
(Elsevier, 2021-04-20)
The shift to electric mobility necessitates recycling the metals from lithium ion battery waste. Ion exchange was studied for use in the removal of impurities from synthetic lithium ion battery waste leachate in laboratory-scale ...
Chromatographic Separation of Rare Earth Elements as MGDA Complexes on Anion Exchange Resins
(MDPI, 2023-03-16)
Chromatographic separation of rare earth elements (REE) as anionic complexes with chelating aminopolycarboxylate ligand methylglycine N,N-diacetate (MGDA) was studied experimentally. A synthetic mixture of La, Nd, and Eu ...
Analysis of reactor–separator processes for polymeric and oligomeric degradation products with controlled molar mass distributions
(Elsevier, 2020-09-18)
Integration of reaction and separation is attractive in production of biobased oligomers and short polymers from polysaccharides and proteins via catalytic degradation. The challenge lies in controlling the molar mass ...
Compost: Potent biosorbent for the removal of heavy metals from industrial and landfill stormwater.
(Elsevier, 2020-07-13)
Stormwater can be contaminated with heavy metals and low-cost solutions are needed to treat large amounts of water. This study was conducted to determine the viability of compost as an adsorbent in Nordic conditions to ...
Solvent Extraction for Separation of 99.9% Pure Cobalt and Recovery of Li, Ni, Fe, Cu, Al from Spent LIBs
(MDPI, 2022-06-20)
In this work, hydrometallurgical recycling of metals from high-cobalt-content spent lithium-ion batteries (LIBs) from laptops was studied using precipitation and solvent extraction as alternative purification processes. ...
