摘要：

Germanium (Ge) exhibits excellent optical and electrical properties. Due to the low reserves of Ge and lack of independent mineral resources, zinc refinery residues have become an important source of Ge. In this work, a D201 x 7 resin has been employed in the selective separation of Ge from a sulfuric solution using tartaric acid as a complexing agent. In the sulfuric acid system, Ge(OH)4 was converted to an anionic complex [GeO2(OH)2C4H4O4]2- at a 1:1 tartaric acid to Ge molar ratio. The anion exchange D201 x 7 resin adsorbed the Ge tartrate anionic complex. The adsorption process exhibited p...
