| Abstract: | Enthalpies of solution of L-alanine in water and aqueous solutions of LiNO3, NaNO3, KNO3, NaClO4 and Na2SO4 were determined at T=298.15 K by a RD496-Ⅱ microcalorimeter. The transfer enthalpies (ΔHtr) of L-alanine from water to aqueous solutions of salts were derived and discussed in terms of the electrostatic interaction and the structural interaction. |
