A novel kind of organosilica functionalized with dicyclohexano-18-crown-6 (DCH18C6) was synthesized in this study. The DCH18C6 molecule, well known as an excellent complexing agent of strontium, was modified for chemical bonding to the organosilica matrix via a co-condensation approach. 29 Si and 13 C solid-state NMR, ESEM and N2 adsorption-desorption measurement were employed to characterize...
A brief status of the development of actinide separation in china is presented. The activities on actinide separation include:1) Neptunium chemistry and its separation in Purex Process;2) actinide separation from HLLW;3) separation of actinides from rare earth; and4) preliminary studies on uranium cathode deposit by pyrochemical process.
