Metals have been incorporated into polymers in a variety of ways. In this study cobalt will be indirectly attached to a polymer matrix via cobalt diacarbollide. Cobalt dicarbollide, [(C2B9H11)2Co]_M+ (CoB2), is a sandwich molecule analagous to ferrocene where Co3+ is sandwiched between two carbollide (C2B9H11 =) cages as depicted in Figure 1. Cobalt dicarbollide has been chosen for its demonstrated ability to selectively extract cesium and strontium from solutions containing a mixture of metals. Unfortunately hazardous organic solvents such as nitrobenzene or ethyl acetate are utilized in the extraction process. It is hoped that by incorporating CoB2 into a polymer matrix that it will act as an ion exchange resin selective towards cesium and strontium, without the need of any organic solvents.
