Abstract
A study of the adsorption of metal ions, in acid sulfate media, on a strong acid type cation exchange resin, Dowex 50W-X8 indicates that the difference between the distribution coefficients of SC(III) and many other ions is sufficiently large for good separation. This fact makes it possible to develope a cation exchange chromatographic procedure for the separation of SC(III)_from other ions. SC(III) can be eluted with 0.3 M (NH4)2SO4—0.025 M H2SO4, while Al(III), Ca(II_), Cd(II) Co(II), Cr(III), Cu(II), Ga(III), Mg(II), Mn(II), Ni(II), Y(III) and the rare earths, and Zn(II) remain adsorved on the column. Ions forming stable sulfatocomplexes or other types of complex are eluted in the effluent from the sample solution. Suitable elution systems for these ions are given. Separation of SC(III) from 23 metal ions is reported.
