Abstract

ABSTRACT : The interaction of Zn(II), Cd(II) and Pb(II) ions with nitrilotriacetic acid (NTA) as a primary ligand,
5-aminotetrazole, 1-H tetrazole and 5-mercapto-1-methyletetrazole, 1,10-phenanthroline and 2,2'-bipyridyl as secondary ligands has been studied in aqueous medium at room temperature. The formation constants for all metal complexes were evaluated using potentiometric titration data. The stability constants were found to depend markedly on the basicity as well as the steric effect of the ligands. يتضمن البحث دراسة تراکب أيونات عناصر الزنک والکادميوم والرصاص الثنائية مع نيتريلوثلاثى حمض الخليک وبعض مشتقات التترازول في الوسط المائي. وتم حساب ثوابت تکوين المتراکبات عن طريق المعايرات الجهرية، وتبين أن القيم المقدرة تعتمد علي قاعدية المرکبات العضوية.
