Relative Solution Equilibria and Chemical Speciation study of Divalent Manganese and Cobalt Ternary complexes with Azelaic acid dihydrazide (AZDH), L-Proline & L-Lysine

Abstract

A solution equilibria study of ternary systems containing Mn2+ and Co2+ with Azelaic acid dihydrazide (AZDH) as L and α-amino acids L - Proline and L - Lysine as X of type [MmLlX xHh], was carried out with the help of potentiometric method for data acquisition followed by chemometric modelling studies, (where m = 1, 2; The SOPHD programme is used to generate relative simulation and titration curves. The speciation analysis and evaluation of formation constants (303K and 0.01M ionic strength) were computed with the MINIQUAD-75 computer software, and concentration distribution graphs were generated with the HySS programme. Various statistical parameters were considered to choose the best-fit chemical models. The ∆log K formulation was used to compare the stability of ternary compleyxes with binary complexes.
