Peculiarities of different-ligand complexing of rare earths with nitrilotriacetate and adenosine-5'-triphosphate according to the mathematical simulation data

By the method of pH-metric titration using mathematical simulation different-ligand complexing of rare earths with nitrilotriacetate and adenosine-5'-triphosphate is studied. It is shown that the ligands interact with the formation of protonated associates. The composition of different complexes is determined, their stability constants are calculated, their existence regions are found
