KCl effect on the solubility of five different amino acids in water

Pitzer and Pitzer–Simonson–Clegg modeling approaches: Ternary HCl+1-propanol+water electrolyte system

“…The results show that the lowest value of (RMSD) is obtained by the extended composition dependent form of the Y 1nMX parameter proposed by Hu and Guo (with b = −1/4 and c = −1/4) for the investigated ternary system. Note that besides the present results and the work of Hu and Guo [10], Ferreira et al [12] have also used an extended composition dependent for Y 1nMX to fit the experimental data related to the KCl effect on the solubility of five different amino acids in water.…”

“…A survey of literature shows, as well, that the application of a complete PSC approach for modeling electrolyte in mixed solvent systems is limited only to the work of two research groups [10][11][12]. This might be due to the apparent complexity of the related relations, the number of involved ion-interaction parameters, and would explain why some authors have used simplified version of the PSC models [13][14][15][16][17][18][19].…”

Solubility of l-serine, l-threonine and l-isoleucine in aqueous aliphatic alcohol solutions

“…The experimental procedure is very similar to that published previously [1,23,24] and so, only brief details are given here. It consists in the preparation of a saturated solution at constant temperature (±0.1 K).…”

“…When w alcohol < 0.8, the gravimetric method is used. Each experimental point is an average of at least three different measurements obeying the following criterion: the quotient 2s/solubility × 100 should be lower than 0.2, where s is the standard deviation within a set of different experimental results [1,23,24].…”

Solubility and Seeded Metastable Zone width of functional sugar L-arabinose

“…Ferreira et al (2007) stated that the solubility of five amino acids increased with the increase in potassium chloride concentration from 0M to 1M (7.45%). Accordingly, in the present study, it was found that the solubility of L-arabinose in the potassium chloride-water system is higher than that in the pure water system at all temperatures tested, and the increment was: 4.0% Potassium chloride > 2.0% Potassium chloride > 1.0% Potassium chloride.…”
