Abstract
The stability constants of ternary complexes of theMAL type have been determined for Cu(II), Zn(II) and Cd(II). The ligands chosen for this study belong to the biologically important ones viz. Bipyridyl (A) and Nitrilotriacetic acid (L). LogK MAL values for Cu(II), Zn(II) and Cd(II) are 11.42, 10.67 and 9.72, respectively, at temp.=25°C and μ=0.1M (KNO3); the order is discussed.
Zusammenfassung
Die Stabilitätskonstanten für Cu(II)-, Zn(II)- und Cd(II)-Komplexe vom TypMAL wurden bestimmt. Die biologisch relevanten Liganden, die für diese Untersuchung ausgewählt wurden, waren Bipyridyl (A) und Nitrilotriessigsäure (L). Bei einer Temperatur von 25°C und μ=0,1M (KNO3) sind die entsprechenden logK MAL -Werte für Cu(II), Zn(II) und Cd(II) 11,42, 10,67 und 9,72; diese Reihenfolge wird ebenfalls diskutiert.
