The College of Science, Kirkuk University discussed a Ph.D. thesis on preparing and characterizing several Schiff base complexes and their activity as corrosion inhibitors for steel by the postgraduate student, Mr. Ahmed Ghadhban Ahmed.
The thesis highlighted preparing several ligands derived from Schiff bases (L1–L6) through the reaction of various aromatic amines and aldehydes. These ligands were characterized using advanced physical and spectroscopic methods. The dissertation also explored the preparation of novel metal complexes with divalent metal ions, including Cd(II), Zn(II), Cu(II), Ni(II), and Co(II).
The thesis demonstrated that the prepared complexes have different geometric shapes depending on the type of metal and ligand, while being electrically neutral. Biological tests also showed a clear inhibitory effect of a number of compounds against Staphylococcus aureus bacteria compared to E. coli
bacteria.
