Synthesis and study of arginine-containing manganese and zinc chelates

Abstract

Synthesis conditions have been established and arginine-containing manganese and zinc chelate compounds have been synthesized with general formula: Me (Arg)n(CH3COO)2·mH2O, where Me=Mn, Zn; Arg- neutral molecule of arginine; n=1÷3; m=1÷4. Synthesized chelates have been studied using a number of physical-chemical researches. In particular, composition has been identified via trace element analysis, while the individuality has been established through fusion temperature measurement and diffractometric method. According to qualitative solubility research, chelates are highly soluble in water, but poorly soluble in organic solvents. Dissociation constant for chelate compound-containing solutions has been calculated using conductometric study method. With the purpose of biological activity research, on the basis of preliminary trial tests an opinion is expressed that entry of arginine-containing manganese and zinc chelates into composition of broilers’ combined feed premixes has had a positive effect on birds’ live weight gain and their preservation. There is expressed an opinion on the reasonability of main tests conduction in order to identify the optimal doses of arginine-containing manganese and zinc chelate compounds for broilers.
