Synthesis and study of arginine -containing citrates

Different-ligand chelate compounds with a general formula Me(Arg)_n·HL·mH₂O,  where Me=Co, Cu, Cr;  n=1÷2; m=0÷4, HL – citrate-ion, have been synthesized. The synthesized compounds have been studied using a number of physical and chemical methods. The composition has been established via trace element analysis, while the individuality – by the methods of melting temperature measurement and X-Ray-diffractometric study. Using the method of conductometric study there have been measured chelate dissociation constants and determination coefficients. Qualitative solubility of chelates in different solvents has been determined. In order to establish the biological activity of the synthesized chelate compounds, an effect of premixes prepared on the basis of chelate compounds, on some hematological indicators of rabbits’ blood has been studied.
