Study of Stability Constants of Fe (III) and Mn (II) Complexes With Chloramphenicol by Paper Electrophoretic Technique
نویسنده
چکیده
Stabilty constant of binary complexes of Fe(III) and Mn(II) with medicinally important ligand chloramphenicol antibiotics in solution were determined by paper electrophoretic technique. Stability constant of the complexes were determined at 25°C temperature and 0.1M (HClO4) ionic strength. Our study is based upon the migration of a spot of metal ions on a paper strip at different pH against mobility gives information about the binary complexes and permits to calculate their stability constant. The stability constant data revealed that chloramphenicol may be used as chelating agent in chelation for medical treatment of metal overload or poisoning.
