“…In both cases, the j s values decrease with increasing amino acid concentration (supplementary data is given) signifying an electrostatic effect of the amino acid on the surrounding medium [28], which makes the solution rather incompressible. This type of observation is characteristic of electrolytic behavior as found in the literature for various systems [25,[29][30][31]. Similar behavior has also been found in the case of aqueous drug-surfactant, protein-surfactant systems [2].…”

Densities (d) and sound velocities (v) of an ethoxylated alkyl phenol surfactant in aqueous solutions of two amino acids, namely glycine and leucine, have been measured over a temperature range of 25-40°C at intervals of 5°C by using density and sound analyzers. Experimental data have been used to calculate the isentropic compressibilities (j s ), apparent molar volumes (/ v ) and apparent molar adiabatic compressions (/ j ) in order to explain amino acid-surfactant interactions. The results have been discussed in terms of the effect of amino acids on the micellization behavior of the surfactant. A comparative study of both the amino acids has been carried out and is found that both amino acids produce a decrease in the CMC value of nonionic surfactant but to different extents.

Ultrasonic velocities and densities of some copper(I), silver(I), and tetrabutylammonium salts have been measured in the concentration range of (0.002 to 0.28) m in binary mixtures of acetonitrile (AN) + adiponitrile (ADN) containing 1.0, 0.9, 0.8, 0.7, 0.6, and 0.5 mol fraction of AN at 298.15 K. The isentropic compressibility (κ s ) and apparent molal isentropic compressibility (κ s,φ ) in various solvent systems have been calculated by using ultrasonic velocity (u) and partial molal volume (V φ ) data, respectively. Limiting apparent molal isentropic compressibilities (κ s,φ o ) for various salts have been evaluated from κ s,φ versus m 1/2 plots and split into the contributions of individual ions (κ s,φ o ) ( . The (κ s,φ o ) ( values for copper(I) and silver(I) ions are found to be negative over the entire solvent composition range which indicates strong solvation of these ions. The (κ s,φ o ) ( values becoming more and more negative with an increase in the ADN composition shows that the extent of solvation increases with an increase in ADN composition. The large and positive (κ s,φ o ) ( values for Bu 4 N + and Ph 4 B -indicate some special type of interaction with the solvent molecules, which increases with the increase of ADN composition in the mixture.
