摘要
The physicochemical properties of amino acids like L-Leucine and L-Serine in aqueous solution of ammonium dihydrogen Phosphate (ADP) at different temperature analysed by volumetric and acoustic methods. By using density data, apparent molar volume V-phi, partial molar volume V-phi(0) and standard partial molar volume of transfer Delta V(phi)(0 )have been evaluated. From speed of sound data, apparent molar isentropic compression K-phi,K-s apparent partial molar isentropic compression K-phi,s(0) and partial molar isentropic compression of transfer Delta K-phi,s(0) have been calculated. The pair and triplet interaction coefficient have also been calculated. The results have been interpreted in terms of solute-solute and solvent-solvent interactions. (C) 2020 Elsevier Ltd.
