This report describes the testing of some novel separations materials known as SuperLig{trademark} materials for their ability to separate efficiently and selectively certain metal ions from a synthetic, nonradioactive nuclear waste solution. The materials, developed and patented by IBC Advanced Technologies, are highly selective macrocyclic ligands that have been covalently bonded to silica gel. The SuperLig{trademark} materials that were tested are: (1) SuperLig{trademark} 601 for barium (Ba{sup 2+}) and strontium (Sr{sup 2+}) separation, (2) SuperLig{trademark} 602 for cesium (Cs{sup +}) and rubidium (Rb{sup +}) separation, (3) SuperLig{trademark} 27 for palladium (Pd{sup 2+}) separation, and (4) SuperLig{trademark} II for silver (Ag{sup +}) and ruthenium (Ru{sup 3+}) separation. Our observations show that the technology for separating metal ions using silica-bonded macrocycles is essentially sound and workable to varying degrees of success that mainly depend on the affinity of the macrocycle for the metal ion of interest. It is expected that ligands will be discovered or synthesized that are amenable to separating metal ions of interest using this technology. Certainly more development, testing, and evaluation is warranted. 3 figs., 11 tabs.
