Discussion of a master’s thesis
The Department of Chemistry at the College of Education for Pure Sciences / University of Karbala discussed the master’s thesis entitled (Estimation of some metal ions and their spectroscopic study using the Schiff base or azo base Schiff reagent) by the student (Alaa Abd Ali Nayef), and under the supervision of Prof. Munir Abd al-Aali Abbas al-Dama’i and Professor Saleh Hadi Kazem. The objective of the thesis was to prepare a new reagent from azo compounds using the traditional nitrogen method, study its coordination sites with Co,Ni,Cu ions, find out its chelating behavior using modern spectroscopic techniques, and conduct a spectroscopic study of the selected metal ion complexes under study using ultraviolet-visible rays, then determine the maximum absorption wavelength for the complexes. The ions under study and the best conditions for the formation of complexes were studied, then the solid complexes were prepared and diagnosed by Uv-vis, IR, HNMR techniques, and the magnetic sensitivity and electrical conductivity of these complexes were studied, and then the structural formulas of the prepared complexes were proposed. The thesis concluded that this analytical method is sensitive, easy, fast, accurate, precise, and selective, and does not require any complications or prior preparations.
The discussion came out with recommendations, including: studying the possibility of using the detector in the estimation of other ions in different media to form colored complexes that are useful in spectral estimation in the fields of medicine and medicine, as well as the possibility of using it in extracting some transitional elements due to its ability to coordinate with many of these ions, and the use of this analytical method In other applied fields with the elements with which the reagent interacts, such as water, soil, pharmaceuticals and foodstuffs, etc., and studying the papological effectiveness of the prepared reagent because it contains the effective azomethine group and the possibility of investing pressing reactions to prepare new reagents that are sensitive and accurate to estimate the ions under study. And the possibility of coupling this method with cloud point extraction methods for the determination of Co,Ni,Cu ions by methods with high sensitivity. The student received an honors grade.
