JAIN, Anubhuti  e  UPADHYAYA, Sanjay K.. Ultrasonic Studies on the Molecular Interactions of Uranyl Soaps in Benzene-dimethylsulphoxide Mixture. Port. Electrochim. Acta [online]. 2013, vol.31, n.4, pp.241-248. ISSN 0872-1904.  https://doi.org/10.4152/pea.201304241.

The ultrasonic measurements of solutions of uranyl caprylate and laurate in a mixture of 50/50 benzene-dimethylsulphoxide (V/V) have been used to determine the critical micellar concentration, ultrasonic velocity and various acoustic parameters at different temperatures. The results confirm that there is a significant interaction between uranyl soaps and the mixed organic solvent molecules.The values of critical micellar concentration of uranyl caprylate and laurate are in good agreement with those obtained from conductivity measurements.

Palavras-chave : ultrasonic velocity; uranyl caprylate; uranyl laurate; acoustic parameters; critical micellar concentration.
