摘要：

The stability constants of triply charged lanthanide ion complexes with citric acid of 1 : 2 stoichiometry were measured by potentiometric titration in a wide pH range, and the relationship between the constants and the lanthanide type was analyzed. A mathematical model for the equilibrium in studied solutions was proposed.
