Abstract

The paper addresses the oxidative characteristics of ozone and the possibility to obtain actinides in highest oxidation states. Mechanisms of direct and indirect oxidation of actinides by ozone are discussed. In alkaline solutions, the ozonide ion radical O3− acts as a strong oxidizing agent and its potential is 1.482 V. The optimal conditions for the formation of actinides in highest oxidation states include concentrated alkaline solutions and low temperatures (− 30 °C or lower), which markedly increases their stability.
