Abstract

The distribution of scandium and hafnium between 0.1 or 1.0 mol l<sup>-1 </sup>HNO<sub>3 </sub>and solutions of monoalkyl methanephosphonates (HA; alkyl = methyl, propyl, butyl, isobutyl, pentyl, 2-methylbutyl, cyclohexyl, 1,2,2-trimethylpropyl) in chloroform and 1,1,2,2-tetrachloroethane has been studied. The organic solvents mentioned allow to obtain the optimum values of partition coefficients of the two metals. The corresponding extraction constants of the ScA<sub>3</sub>(HA)<i><sub>x</sub></i> and Hf(NO<sub>3</sub>)<sub>4</sub>(HA)<sub>4 </sub>complexes have been calculated.
