Separation of copper(II) from uranium(VI) and many other elements by cation- exchange chromatography in acetone-hydrobromic acid media. Improved selective separation of copper
Co(II), Ni(II), Mn(II), Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Ti(IV), V(IV), Zr, Hf, Th, Al, Sc, Y, La, the lanthanides and also U(V), which accompany copper(II) in hydrochloric acid --acetone mixtures, can be separated from copper by eluting copper(II) with 0.50 M hydrobromic acid in 65% acetone from a column of AG 50W-X8 resin, 200-400 mesh, while all these elements are retained by the columm quantitatively. Separations are sharp and quantitative, as is demonstrated by results for some synthetic mixtures. Some relevant elution curves are presented. (auth) The capacities for a rapid separation of radioactive species by isotopic ion exchange was examined. A radioactive element trace cam be removed from a large radioactive matrix by passing the mixture solution through a column previously saturated with the same stable cation of the matrix. The major radioactive matrix component M/sup x/ is retained on the cation exchange resin RM by isotopic exchange while the other radioactive components are easily eluted. The limits of the method have been approached by using four different matrices from high to low ion exchange selectiviiy. (auth)
