Abstract
Adsorption of Pb(II) from nitric acid solution onto gel spheres of zirconium hydroxide and of a solid solution of zirconium and calcium hydroxides was studied. The Pb(II) distribution coefficient on zirconium hydroxide gel spheres at pH 6.0 ± 0.2 is high, 4 × 104 cm3 g−1. For the gel spheres of a solid solution of zirconium and calcium hydroxides, the distribution coefficient is appreciably lower, but the sorption capacity is considerably higher. These features are due to formation of a solid solution of lead and zirconium hydroxides in the course of sorption.
