    Occurrence and behaviour of silver nanoparticles in the environment: analytical methodologies and laboratory studies 

    Torrent Fàbrega, Laura (Date of defense: 2019-10-09)

    The production of engineered nanomaterials (ENMs) has grown in last years due to their special physicochemical properties in respect to their bulk counterparts, derived from their small size (1-100 nm). Among the existing ...

    Pollution assessment of arsenic in groundwater: geochemistry and analytical aspects 

    Majumder, Santanu (Date of defense: 2013-10-30)

    Apart from the geological controls that can cause As mobilization in groundwater in the Bengal Delta Plain, local anthropogenic factors may also contribute to some extent. Investigations showed that As(III) get enriched ...

    Removal of pharmaceuticals in wastewater combining different treatment technologies: suspect screening identification and risk assessment of transformation products 

    Jaén Gil, Adrián (Date of defense: 2021-05-28)

    The low efficiency of wastewater treatment plants to achieve the complete removal of micropollutants, including pharmaceuticals, has motivated the development of alternative water technologies to improve their efficiency, ...

    Síntesis y caracterización de materiales poliméricos para la separación no cromatográfica de metales nobles. Separación y determinación de iridio mediante cromatografía líquida y electroforesis capilar 

    Sánchez Navarro, Juan Manuel (Date of defense: 1999-03-17)

    For the selective separation of Noble Metals, different new chelating polymers with the same functional group, based on tri-isobutylphosphine sulphide, have been synthesised. Different spacers between the polymeric matrix ...

    Target analysis and suspect screening of wastewater derived contaminants in receiving riverine and coastal areas and assessment of environmental risks 

    Čelić, Mira (Date of defense: 2020-12-15)

    The main objective of this thesis is to evaluate the impact of wastewater discharges on receiving riverine and coastal ecosystems by studying the occurrence and fate of emerging contaminants (ECs). Since there is a myriad ...

    Utilització de suports polimèrics en processos de separació de metalls valuosos. Aplicacions hidrometal.lúrgiques i analítiques 

    Iglesias Juncà, Mònica (Date of defense: 2000-03-03)

    The present study focuses on the characterization of solid-liquid extraction techniques for the separation and preconcentration of rare-earth elements and precious metals. We developed an impregnated resin with di ...
