IPC: C22B13/06
Filed: 1987-12-22
Abstract: PURPOSE:To effectively refine lead in a relatively short time at a low cost by dissolving high-grade lead in water as the lead nitrate, bringing the soln. into contact with a multiple adsorbent consisting of hydrated titanium oxide and activated carbon, neutralizing the soln., and then reducing the obtained lead compd. CONSTITUTION:The lead having >=99.99% purity such as commercial electrolytic lead is dissolved in hot concd. nitric acid, and then cooled to deposit lead nitrate. A soln. of the lead nitrate in pure water is brought into contact with the multiple adsorbent consisting of hydrated titanium oxide and activated carbon. The adsorbent is obtained by impregnating activated carbon with TiCl4, and hydrolyzing the TiCl4 to form hydrated titanium oxide in the pores of activated carbon. The radioactive elements in the raw lead is effectively adsorbed by the adsorbent and removed by contact. The aq. soln. is then neutralized with an alkali to form and precipitate an insoluble lead compd. The recovered precipitated lead compd. is reduced in a gaseous hydrogen current. As a result, metallic lead with a small alpha-ray radiant quantity is obtained.
