Abstract

Measurements were performed to determine the solubilities of L-histidine in aqueous solutions of various concentrations of chloride salts (NaCl and KCl) by using a thermostatted reactor and gravimetric method from (293.15 to 323.15 K) under atmospheric pressure. The effect of inorganic salts on the solubility of L-histidine was investigated and was found accordingly: sodium chloride > potassium chloride. Results showed that the solubility in pure water and in aqueous chloride solutions increased with increasing temperature. The experimental data were well correlated by the semi-empirical equation. Using the measured solubilities, the standard molar thermodynamic properties of transfer of GA (ΔtrGo, ΔtrHo and ΔtrSo) from pure water to aqueous solutions of the chloride salts were estimated
