Sonochemistry of actinides: from ions to nanoparticles and beyond

Abstract Sonochemistry studies chemical and physical effects in liquids submitted to power ultrasound. These arise not from a direct interaction of molecules with sound waves, but rather the acoustic cavitation: nucleation, growth, implosive collapse microbubbles The violent implosion bubbles leads formation chemically reactive species. In principle, each cavitation bubble can be considered as microreactor initiating reactions at mild conditions. addition, microjets shock waves accompanied produce fragmentation, dispersion erosion solid surfaces or particles. Microbubbles oscillating also enable nucleation precipitation nanosized actinide compounds specific morphology. This review focuses on versatile sonochemical processes ions particles homogenous solutions heterogenous systems. redox aqueous solutions, dissolution refractory solids, synthesis nanoparticles, ultrasonically driving decontamination are considered. guideline for further research is discussed.
