Selection of solvents with A-UNIFAC applied to detoxification of aqueous solutions
(American Chemical Society, 2014-07)
In this work, a molecular design of solvents program based on A-UNIFAC, a revised UNIFAC model where specific association interactions are taken into account, is applied to the removal of organic chemicals found in wood ...
Glass transition of LiCl aqueous solutions confined in mesoporous silica
(American Institute of Physics, 2019-08)
The thermal transitions of confined LiCl aqueous solutions were studied by differential scanning calorimetry for solutions with salt concentrations with eutectic (R = 7) and subeutectic (R > 7) compositions (R = moles of ...
Impact of temperature changes and pH on aqueous solutions of TCAB, a derived propanil contaminant
(Pergamon-Elsevier Science Ltd, 2019-11)
3,4,3′,4′-tetrachloroazobenzene known as TCAB is an unwanted product derivate from the degradation of propanil herbicide. In this work UV–visible and infrared spectroscopies were used to experimentally explore the impact ...
Rate constants of quenching of the fluorescence of pterins by the iodide anion in aqueous solution
(Elsevier Science, 2012-07)
The fluorescence of various pterins (6-methylpterin, 6-hydroxymethylpterin, 6-formylpterin, and 6-carboxypterin) was quenched using iodide in neutral, aerated neutral phosphate buffer. Stern-Volmer plots and the fluorescence ...
Carbon-based sorbets for heavy metal removal from aqueous solution, discrepancies, and future prospects: a state-of-the-art review
(Springer, 2021-08)
Heavy metal contamination is severely affecting human health and environment. These metals are known to exist naturally but the anthropogenic activities have contributed towards increasing their concentrations beyond ...
Crystal Growth from Aqueous Solution in the Presence of Structured Impurities
(American Chemical Society, 2019-01)
A kinetic model describing crystal growth from aqueous solution in the presence of structured impurities is developed on a generalization in the spirit of the Davey and Mullin model. The proposed theoretical framework ...
Viscosity of supercooled aqueous glycerol solutions, validity of the Stokes-Einstein relationship, and implications for cryopreservation
(Academic Press Inc Elsevier Science, 2012-10)
The viscosity of supercooled glycerol aqueous solutions, with glycerol mass fractions between 0.70 and 0.90, have been determined to confirm that the Avramov-Milchev equation describes very well the temperature dependence ...
Thermodynamics of non-reactive gases dissolved in water at ambient temperature (T≤333 K): an update
(Springer/Plenum Publishers, 2008-10)
The thermodynamics of dissolution of non-reactive gases in water under ambient conditions is of importance for the description of the properties of small hydrophobic solutes, and they are also of interest for environmental ...
Equilibrium properties of charged spherical colloidal particles suspended in aqueous electrolytes: finite ion size and effective ion permittivity effects
(Academic Press Inc Elsevier Science, 2012-08)
The equilibrium properties of a charged spherical colloidal particle immersed in an aqueous electrolyte solution are examined using an extension of the Standard Electrokinetic Model that takes into account the finite ion ...
Evaluation of Water Activity in H2O-PEG400-PEG6000 Solutions between 318.15 and 348.15 K
(American Chemical Society, 2018-05)
The vapor pressure of H2O(1)-polyethylene glycol 400(2)-polyethylene glycol 6000(3) solutions was evaluated experimentally in a temperature range between 318.15 and 348.15 K and in a broad range of concentrations. The ...
