Adsorption of contaminants on hydrochar derived from biomass via hydrothermal carbonization
(2025)In this study, fermented grain (FG) and sewage sludge (SS) were hydrothermally carbonized (HTC) to produce hydrochars (HCs). The obtained HCs were then chemically modified (MHCs) by impregnation. The chemical composition ... -
Adsorption of phosphorous and arsenic oxyanions to metal hydroxide and oxide surfaces
(2021)This study focuses on two quite distinct elements, phosphorous and arsenic, and their removal from aqueous solutions by adsorption. On the surface, one could assume there is not much common with these two elements. Phosphorous ... -
Adsorption of rare earth elements on novel “Mg-Al layered double hydroxide with gum arabic”
(2018)In the last few decades, the demand for rare earth elements has increased, as there have been further discoveries for their use. Rare earth elements are used for very specific applications and can be extracted from different ... -
Advanced membrane-based technology for the separation of valuable metals through ion-selective recognition
(2024)This bachelor's thesis investigates the use of ion-imprinted membranes (IIMs) to separate critical metal ions from lithium-ion battery waste (LiBs). The objective was to identify the variables that influence the effectiveness ... -
Advanced separation materials for lithium recovery from aqueous resources and spent batteries
(2026)The World’s rising demands requires the extraction of lithium from sources that have been previously deemed unobtainable. Aqueous resources such as natural, oilfield and geothermal brines contain considerable amounts of ... -
Advanced synthesis and characterization of metal–organic frameworks for diverse applications
Acta Universitatis Lappeenrantaensis : 1269 (Lappeenranta-Lahti University of Technology LUT, 15.12.2025)Metal–organic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs) represent a remarkable class of porous crystalline materials, distinguished by their highly ordered structures, large surface areas, and chemical ... -
Advancing green mining : integrating sustainable water and tailings management in the copper mining industry
Acta Universitatis Lappeenrantaensis : 1250 (Lappeenranta-Lahti University of Technology LUT, 01.12.2025)Nowadays, the extensive requirement for high-tech products, developing societies based on hyper-connectivity, and deploying low-carbon energies are causing a substantial increase in demand for various critical minerals and ... -
Aikuisille suunnatuissa vaipoissa käytettävät materiaalit ja niiden ominaisuudet
(2019)Nykyaikaiset kertakäyttövaipat ovat osana miljoonien lasten ja aikuisten elämää päivittäin. Ne on valmistettu synteettisistä, inerteistä polymeereistä. Synteettiset polymeerit ovat öljyjohdannaisia ja pysyvät ympäristössä ... -
Air pollution control with metal-organic frameworks (MOFs)
(2023)Air pollution causes approximately 7 million deaths annually. The most significant pollutants are NO₂ and SO₂ due to their abundance and effect on human health as well as the environment. Approximately 98% of SO₂ and 85% ... -
Alkalimetallien termodynaaminen aktiivisuus laimeissa amalgaameissa lämpötilassa 25°C
(2018)Tämän työn tarkoituksena oli määrittää alkalimetalleille 25°C lämpötilassa aktiivisuuskertoimia laimeissa amalgaameissa, käyttäen alkalimetallisuolojen termodynaamisia ominaisuuksia laimeissa vesiliuoksissa ja amalgaami ... -
Alkaliniteetin vaikutus kartongin AKD-liimaukseen
(2023)Taivekartonkia käytetään yhä enemmän pakkausmateriaalina. Pakkauksen on oltava läpäisemätön muun muassa kosteuden suhteen, jotta sitä voidaan käyttää esimerkiksi elintarvikkeiden pakkaamiseen. Kartongin hydrofobisuutta eli ... -
Alternatives for the valorization of isocyanate derived residual products from the glycolysis of polyurethane
(2024)Polyurethane is among the most popular six polymers that are employed most frequently. So, at the end of its usage, a huge amount of material was produced as waste. One of the most intriguing options for polyurethane foam ... -
Ammonium nitrogen recovery methods in various wastewater matrices
(2024)Need for nitrogen in food production rises now and in the future as the world’s population grows even more. The production of nitrogen fertilizers is usually made by Haber-Bosch process which consumes much energy and causes ... -
Ammonium-based eutectic solvents for the fractionation of woody biomass
(2025)The sustainability of bioproducts hinges on the sustainable sourcing of their raw materials, such as lignocellulosic components—cellulose, hemicellulose, and lignin. In this context, lignocellulosic biomass (LCB) is a ... -
