Study of triglycine complexation with Cu2+ ions in aqueous solution

Аннотация

Composition and stability of triglycine complexes with Cu(II) ions in a wide range of concentration ratios at T = 298.15 K and I = 0.2 (KNO₃) have been determined by potentiometric method. Existence of CuHL²⁺, CuHL₂₊, CuH₂L²⁺², CuL⁺, CuH_–1L, CuH_–2L–, CuH_–3L^2–, CuL₂, CuH_-1L^-₂, and CuH_–2L^2-₂, species has been established.
