Description
  • The extraction of micro amounts of cesium by nitrobenzene solutions of sodium, potassium and rubidium dicarbollylcobaltates (M(+)B(-);M(+)=Na(+),K(+),Rb(+)) has been investigated in the presence of 2,3-naphtho-15-crown-5 (N15C5, L). The equilibrium data were explained by assuming that ML(+) and ML (2) (+) complexes (M(+)=Na(+),K(+),Rb(+), Cs(+); L=N15C5) were present in the organic phase. The stability constants of the complex species ML(+) and ML (2) (+) have been determined in nitrobenzene saturated with water. It was found that the stability of the complex cation ML(+) (where M(+)=Na(+),K(+),Rb(+), Cs(+); L=N15C5) in water-saturated nitrobenzene solutions increases along the series Cs(+)< Rb(+)< K(+)< Na(+), whereas that of the species ML (2) (+) in the same medium increases in the order Cs(+)< Rb(+)< Na(+)< K(+).
