Abstract: | A new reagent for the highly selective extraction of cesium (e-1,7 –2,2 )4,8 –8,4 -(bis- -o-phenylene)bisdicarbollidocobalt(1–)ate, (C2B9H9)2(C6H4)2Co]–, abbreviated as BISPHECOSAN is described in this paper. The choice of organic solvent and solubilizer, dependence of distribution ratio of Cs+ on acidity and other parameters are studied. The extraction mechanism based on selective binding of Cs+ cation between two phenylene rings is presented and factors influencing the chemical stability of the reagent are determined. |
