Purification of Europium. An acetate solution obtained from 20 g. of europium(III) oxide (>99% pure) was treated with 260 ml. of 0.3% sodium amalgam, added in three separate equal portions. The resulting amalgam contained all but 0.09 g. of the europium. Treatment of the amalgam with 100 ml. of 10 M hydrochloric acid caused complete precipitation of europium(II) chloride 2-hydrate. Removal of the product followed by washing with ice-cold 10 M hydrochloric acid and ultimate conversion to euro-pium(III) oxide gave a recovery of spectroscopically pure europium in excess of 90%. [Pg.37]
