Abstract

Reactions of GeO2 with eight chelones were studied in dilute aqueous solutions by using the potentiometric neutralization titration method. The equilibrium formation constants were determined for the Ge(OH)Y- and Ge(OH)(HY) complexes with EDTA, Ge(OH)2Z- complex with NTA, and Ge(OH)(OH2) complex with TEA. The conditions for formation of Ge(IV) chelates with chelones are discussed.
