A dissertation in the College of Science at the University of Kerbala entitled “Spectral Estimation of Tiny Quantities of Zinc Binary Ions and Triple Chromium Using Imidazole Dyes Derivatives” to study the Thermodynamic Functions and Their Analytical Applications discussed the spectroscopic determination of trace amounts of zinc(II) and chromium(III) ions using imidazole dye derivatives, by Student Hawra Abdel-Hadi Abdel-Amir, including three chapters, which are an introduction, the practical part, and results and discussion, preparing and diagnosing a new ligand that is (SDPIHN) by the traditional nitrogenization method. This study also dealt with the use of this detector for the spectroscopic determination of zinc and chromium ions in the presence of the activated substance for surfaces. The best conditions for the interaction of these ions with the detector were studied, such as the pH function, the volume and concentration of the detector, and the volume and concentration of 100-X Triton.
The study aimed at the possibility of developing a new method for the quantitative determination of zinc and chromium ions using the detector (SDPIHN), knowing the optimal conditions for work measures, estimating the accuracy and compatibility of the proposed method, and comparing it with other complex methods.
The thesis has recommended the possibility of estimating the concentrations of other ions using the SDPIHN reagent in different media and the possibility of producing new derivatives from the reagent to improve the selectivity as well as the possibility of studying the biological activity of the reagent.
