Abstract: Effects of ultrasound on intensification of separation process were investigated through
the experiment of desorption equilibrium behavior. Tri-butyl phosphate (TBP) on NKA-X resin
and phenol on a solvent impregnated resin, CL-TBP resin, were used for desorption
processes. The desorption rate was measured with and without ultrasound. Desorption
equilibrium was studied under various ultrasonic power densities or thermal infusion.
Results showed that the desorption rate with ultrasound was much higher than that with
normal thermal infusion. Both ultrasound and thermal infusion broke the desorption
equilibrium existed at room temperature. However, after the systems were cooled down, the
amount of solute desorbed in the liquid phase in the presence of ultrasound was much higher
than that at the temperature corresponding to the same ultrasound power. It is proved that
the initial desorption equilibrium was broken as a result of the spot energy effect of
ultrasound.

Key words: ultrasound, sorption equilibrium, desorption
