Stability of rare earth complexes with 2-(o-hydroxyphenyl)benzimidazole in aqueous-dioxane medium. Ustojchivost' kompleksnykh soedinenij RZEh s 2-(o-oksifenil)benzimidazolom v vodno-dioksanovoj srede

Abstract

Method of potentiometric titration was used to determine protonation constants of 2-(-hydroxyphenyl)benzimidazole (pK{sub 1}=4.5; pK{sub 2}=11.30) and stability constants of Pr,Nd,Sm,Eu,Tb,Dy complexes with this ligand. Nonmonotonous change of lgK{sub 1} with increase of ordinal number of rare earth element was revealed.
