Magnesium can be separated from calcium by elution with 3.0 IM hydrochloric acid containing 60% ethanol from a column of AGsoW-X8 cation-exchange resin. Calcium is retained and can be eluted with 3.0 IM hydrochloric acid or 2.0 IM nitric acid. The separation factor of OL&~ = 5.6 is considerably high
Lead is separated from gram amounts of Zn, In, Ga, Fe(III), Cu(II), Co(II), Mn(II), U(VI), Ca and Ba on a short column of AGl-X4 anion-exchange resin in the bromide form. Lead is retained from 0.2 M hydrobromic acid while the other elements are eluted completely with this reagent. Lead is then elute
