The Synthesis, characterization and investigation of extraction properties of a new vic dioxcime, containing macrocyclic group, and it's mononuclear Ni(II) complex

The Synthesis, Characterization and Investigation of Extraction Properties of A New vic- Dioxime, Containing Macrocyclic Group, and It's Mononuclear Ni(II) Complex. In this study a new vic-dioxime l,3-Bis(benzo-7,10,13-trithia-l,4-dioxa cyclopentadecane)-2-thia oxa-4,5-Bis(hydroximino)imidazole shown as (5) and it's (LH2) compound and mononuclear nickel from of this compound, [Ni(LH)2], are synthesized(6). The structures of these compounds are characterized by elemental analysis, IR, 'H-NMR, 13C- NMR and Mass spectral data. Alkaline, alkaline earth, transition and heavy metals' extractions from aquous media with the compounds (5) and (6) are investigated depend on their donor atom type, cation size, pH and solvent effects. The results obtained in the extraction studies are given as tables and graphics Li, Na, K, Ca, Ba pictrates of vic-dioxime (5) compound, the extractability values %, and Cu, Cd, Pb, Hg, Ni, Zn picrates of the compound (6), the extractability values % are measured by UV-Vis spectrometer and at the best extractability pH value of Ag existing different solvent, extraction from dual cation systems, selectively, % values are measured by AAS. Furthermore, % extraction values of Ag picrates of the compounds (5) and (6) in chloroform and dichlorometan at different pH values are determined by UV-Vis and AAS.
