Ultrasonic Study of Solvent Extractant in Nuclear Technology

The experimental data of ultrasonic velocity and calculated values of density are used to study the different interactions in the extractants tri-n-butyl phosphate (TBP) with kerosene. The temperature of the system is maintained 303 K and the frequency used to measure the ultrasonic velocity are 1MHz, 3MHz and 5MHz. This study involves evaluation of different thermo-acoustic parameters along with the excess properties, which are interpreted in the light of inter-molecular interaction between polar extractants with non-polar diluents.The variation of these thermoacoustic parameters with concentration and frequency insight the information regarding the extraction process of some rare earth elements (REEs) like yttrium, lanthanum.
