Efficient extraction of Cs and Sr into hydrocarbons using modified cobalt dicarbollide
- Los Alamos National Lab., NM (United States); and others
Processing of defense-related nuclear wastes requires separation of the highly radioactive fission products cesium and strontium from both acidic and alkaline waste streams. The cobalt dicarbollide process, while known to be efficient and selective for Cs and Sr removal from acidic wastes, has received little attention in this country due to the use of toxic nitrobenzene as diluent. By preparing alkyl-functionalized cobalt dicarbollide derivatives, we have developed a system that utilizes non-hazardous, inexpensive hydrocarbons as diluents. The performance of this system in acidic and alkaline media, including distribution coefficients, selectivity over relevant cations, capacity, and chemical stability, will be discussed.
