Decontamination of water co-polluted by copper, toluene and tetrahydrofuran using lauric acid

L Earnden, AG Marangoni, T Laredo, J Stobbs… - Scientific Reports, 2022 - nature.com
Co-contamination by organic solvents (eg, toluene and tetrahydrofuran) and metal ions (eg,
Cu2+) is common in industrial wastewater and in industrial sites. This manuscript describes …

Role of hydrogen bonding on solvent separation using amphiphilic sorbitan ester

B Bartokova, AG Marangoni, T Laredo… - Colloids and Surfaces C …, 2023 - Elsevier
Tetrahydrofuran (THF) and water are miscible and interact trough hydrogen (H) bonds. Span
80 (sorbitan ester) is soluble in THF, but not water. Nonetheless, Span 80 H bonds with …

Mechanism of tetrahydrofuran separation from water by stearic acid

B Bartokova, T Laredo, AG Marangoni… - Journal of Molecular …, 2023 - Elsevier
Stearic acid separates tetrahydrofuran (THF) and water into either bulk phase or emulsions,
above 30% THF (relative to water, v/v). The oxygen on the THF ring interacts with either …

Mechanisms of separation between tetrahydrofuran and water using hydroxystearic acid

L Earnden, AG Marangoni, T Laredo, J Stobbs… - Physics of …, 2022 - pubs.aip.org
Tetrahydrofuran (THF) is fully miscible in water, and it interacts with it via hydrogen (H)
bonds. We discover that the fatty acid hydroxystearic acid (HSA) separates THF from water …

Phase behavior of sulfolane: Potential implications for transport in groundwater

B Bartokova, AG Marangoni, T Laredo… - Colloids and Surfaces A …, 2023 - Elsevier
Sulfolane is a toxic pollutant freely miscible in pure water. However, above benchmark
concentrations of sulfate or thiosulfate ions, it behaves as a light non-aqueous phase liquid …

Self-Assembled glycerol monooleate demixes miscible liquids through selective hydrogen bonding to water

L Earnden, AG Marangoni, T Laredo, J Stobbs… - Journal of Molecular …, 2022 - Elsevier
Water is miscible with dimethylsulfoxide (DMSO), with which it interacts through hydrogen
bonds (H-bonds). Glycerol monooleate (GMO, 53 g/L) demixes water and DMSO, yielding …

Effect of bacterial surfactants on the phase behavior of miscible pollutants in water

V Patel, AG Marangoni, SM Ghazani, T Laredo… - Colloids and Surfaces C …, 2023 - Elsevier
Rhamnolipids are bacterial amphiphiles. In addition to emulsifying hydrophobic solvents,
they affect the phase behaviour of miscible solvents. In mixtures of toluene and water …

Effect of hydrogen bonding on the mixing behaviour of ternary aqueous mixtures

B Bartokova, AG Marangoni, T Laredo, J Stobbs… - Journal of Molecular …, 2023 - Elsevier
This study correlates the solution behaviour of an aqueous mixture to hydrogen bonding
between its three components (water, liquid Pluronic L31 and either tetrahydrofuran, THF or …

[HTML][HTML] Comparison between acetonitrile-water separation by betaine and betaine hydrochloride

E Pensini, AG Marangoni, B Bartokova - Colloids and Surfaces A …, 2024 - Elsevier
Acetonitrile and water are miscible solvents. This study compares their separation by
betaine and betaine hydrochloride. Acetonitrile is a hydrogen (H) bond acceptor and so is …

Effect of sorbitan ester structure on the separation between tetrahydrofuran and water

B Bartokova, AG Marangoni, T Laredo… - Frontiers in Soft …, 2023 - frontiersin.org
This study separates tetrahydrofuran (THF)-water mixtures containing varying THF
percentages, using sorbitan esters (Spans) with different tail characteristics. We probe the …
