Scanometry Method Study, Structural and Spectroscopic Aspects of Schiff Base Ligands Containing N and S Donor Atoms

The tetradentate Schiff base ligand methyl-2-{[1-methyl-2-(aceton) ethylidynenitrilo]ethyl}amino-1-cyclopentenedithiocarboxylate, (H2cdacacMeen), was synthesized and characterized by elemental analysis, IR, 1H NMR, UV-Vis and mass spectrometry. The characterization of the scanometry method [1,2] based sensor membrane is described for the determination of Schiff base ligand on the immobilization of some metals such as Fe, Mn, Cu, and Ni on a triacetylcellulose membrane. The application of silica gel polymer as a reagent for determination of metal ion based on single drop scanometry was described. After mixing sample solution containing Schiff base ligand with silica gel polymer, reaction was done and one droplet of final solution injected on the glass plate, before drying the droplet, glass plate was scanned with flatbed scanner. Image of solution single droplet was analyzed to color values in the various color spaces such as RGB, CMYK, HSL, HSV, XYZ, and correlation between any color values and concentration was studied. The characterization of single droplet, the sampling box location in the single drop and the effect of times on the reaction was studied by scanometry method.
