Measuring and modeling aqueous electrolyte/amino-acid solutions with ePC-SAFT

Chemical Transfer Energetics of a Series of Homologous α-Amino Acids in Quasi-Aprotic 2-Methoxyethanol–Water Mixtures

“…Here the standard deviations (s f ) were estimated for all solubility values to characterize the precision and are shown in Table 1. Here it is important to note that the most of the solubility data of the experimental amino acids in pure water corroborate excellently with the literature data that are summarized in Table S1 [12,19,20,[24][25][26][27][28][29][30][31][32].…”

Compatible solutes: Thermodynamic properties relevant for effective protection against osmotic stress

“…In this work, ν cal was set to two for NaCl/water solutions. Based on our experience with the used apparatus [31], the uncertainty of the VPO method can be estimated to be ± 1% with respect to osmotic coefficients. Experimental data measured in this work by VPO are listed in Tables 4 and 5.…”

Solubility and solvation thermodynamics of dl-nor-valine in aqueous solutions of NaCl and KCl

“…The standard deviations (s f ) for all the solubility values at different temperatures are estimated to draw an idea about the precision of measurements and are presented in the parentheses ( Table 2). In order to examine the reliability of the present method used to determine the solubility, the solubilities of different amino acids under different experimental conditions were evaluated by the current method and compared with the earlier results determined by other analytical methods [3,13,34,35,38,44,45] (Table 3). This clearly shows a reasonable agreement among the values, thereby justifying the method of measurement used in this study.…”

“…For quite a long time, several studies on the solubilities of different amino acids have been carried out in water, in mixed solvents and in both with or without salts using several chemical and thermodynamic models under different experimental conditions [2][3][4][5][6][7]. It has been observed that experimental temperature [2,4], polarity of the solvents [8][9][10], ionic strength [3,11], acidity or alkalinity of the media [4,6,9,12], etc., affect the solubility of amino acids and hence the thermodynamics of solvation significantly. The variation of amino acid solubility with the temperature was explained precisely by using different standard equations and models where the theoretical results were justified with the experimental observations [2,[13][14][15][16].…”
