Synthesis and study of different-ligand chelates

Synthesis conditions have been established and different-ligand chelates have been synthesized with a general formula: [MArg]Hl·nH₂O, where M are bivalent metal ions M = Mn, Zn, Fe, Arg – amino acid arginine, Hl– citric acid bivalent anion, n – number of water molecules. The synthesized compounds have been studied using a number of physical and chemical methods: 

composition – using trace element analysis, while individuality – by the methods of melting temperature measurement and X-ray-diffractometric study. 

Chelate dissociation constants and determination coefficients have been measured by the conductometric research method. Qualitative solubility of chelates in different solvents has been established. 

In order to study biological activity of the synthesized chelates, based on the experiments conducted on broilers it has been established that introduction of the mixture of microelement chelates into composition of broilers’ combined feed premixes has had a positive effect on live weight gain and survival rate of birds.
