摘要

Abstract

Potentiometry and calorimetry are used to study Ce³⁺–glycine–ethylenediaminedisuccinic acid and La³⁺–glycine–ethylenediaminedisuccinic acid systems in aqueous solutions at T = 298.15 K (KNO₃). The formation of a mixed-ligand complex is revealed, and the thermodynamic characteristics (Δ_rH, Δ_rG, Δ_rS) of the complexation reaction are determined.
