THERMODYNAMICS OF COMPLEXATION OF Ni2+ IONS WITH TRIGLYCINE IN AQUEOUS SOLUTION

The composition and stability of complexes of triglycine with ions Ni(II) was deter-mined in a wide range of concentration ratios at T = 298.15 K and I = 0.2 (KNO3) by poten-tiometric and spectrophotometric methods. The existence of particles NiL+, NiH-1L, NiL2 NiH-2L22-, NiL3–, NiH-3L34- was established.
