Abstract

Solution study of chelate compounds of 2-Amino-3-(4-hydroxyphenyl) propanoic acid (2–AHPPA) and 5-methyluracil (5-MU ) with bivalent heavy metal ions Cd (II) and Pb (II) have been completed potentiometrically at a fixed ionic strength I= 0.1M NaNO3 and 37±1oC temperature at silver- silver chloride electrode in biologically relevant conditions. The analysis of stability constant (log ßpqrst) and stability order of investigated metal chelates were done by a specific computer programme SCOGS. The ORIGIN 4.0 deduced the formation of various metal chelate species by sketching the speciation curves for all species separately.
