A master’s thesis at the College of Science at the University of Karbala discussed the preparation and diagnosis of the derivative of the new Schiff rules and their use in the spectroscopic determination of trace quantities of some heavy element ions, the study of thermodynamic functions and their analytical applications. The study presented by researcher Abeer Jassim Saheb aimed to use the prepared reagent for the spectroscopic determination of cobalt(II) and chromium(III) ions and to study the best conditions for the determination of the ions. The study concluded that the estimation of cobalt (II) and chromium (III) ions using the prepared detector has greater sensitivity and accuracy compared to previous studies. The letter recommended studying the biological effectiveness of Schiff bases due to their importance in life processes, due to their effectiveness against cancer, bacteria, and fungi.
