1. Process for selectively removing at least one functionalized organic compound present in a liquid medium, in which a stream of vector gas is circulated in the liquid medium, and the liquid medium is simultaneously subjected to the action of ultrasonic waves which have a frequency from 15 kHz to 1.5 MHz and an acoustic intensity from 1 W.cmto 20 W.cm, whereby gaseous products are predominantly produced, said products being removed from the liquid medium by said stream of vector gas circulating in the liquid medium. 2. Process according to Claim 1, in which the functionalized organic compound(s) has (have) a vapour pressure different from the vapour pressure of the majority constituent of the liquid medium. 3. Process according to Claim 1, in which the flow rate of the stream of gas is from 10 to 600 ml/min. 4. Process according to Claim 1, in which the vector gas is chosen from rare gases, air and mixtures thereof. 5. Process according to Claim 1, in which the temperature and pressure of the liquid medium are from 10 to 100°C and from 1 to 10 bar, respectively. 6. Process according to Claim 5, in which the pressure is atmospheric pressure and the temperature is ambient temperature. 7. Process according to Claim 1, in which the said at least one functionalized organic compound comprises at least one function chosen from functions comprising at least one atom chosen from nitrogen, oxygen, sulphur and phosphorus atoms and halogen atoms such as chlorine, bromine and iodine. 8. Process according to Claim 7, in which the said function is chosen from carboxylic acid, sulphonic acid, phosphoric acid, anhydride, ester, acid halide, amide, nitrile, aldehyde, ketone, alcohol, thiol, amine, ether, organic nitrite, organic nitro and organic nitrate functions and halide functions. 9. Process according to Claim 1, in which the liquid medium is a one-phase medium. 10. Process according to Claim 1, in which the liquid medium is a multi-phase medium, for example a two-phase medium. 11. Process according to Claim 9, in which the one-phase medium consists in an organic phase. 12. Process according to Claim 10, in which the medium is a two-phase medium consisting in an organic phase and an aqueous phase. 13. Process according to Claim 11 or Claim 12, in which the organic phase essentially comprises an organic solvent. 14. Process according to Claim 13, in which the organic solvent consists essentially of an extractant-diluent mixture, used in processes for reprocessing nuclear fuel or processes for cleaning, decontaminating nuclear plants. 15. Process according to Claim 14, in which the extractant is chosen from alkyl phosphates, such as tributyl phosphate (TBP), and alkylamides. 16. Process according to Claim 14, in which the diluent is chosen from alkanes, such as HTP, alcohols, carboxylic acids, and dodecane.
