| Abstract | ||
| New reagent and complex of general formula ML2,where M=Hg(II),L=5-[(hydroxyl phenyl)azo]-4,6-di hydroxyl-2-mercapto primidine) have been prepared in ethanolic solution. Solid compounds were isolated and characterized by electrons and vibrational spectra. A sensitive method has been developed for the determination of micro amounts of Hg(II). The method is based on the chelation of metal ion with the azo dye to form an intens color soluble product, that are stable and has a amaximum absorption at (524 nm),and ε max of(4.01x104 ).The stability constant and relative errors and a relative standard deviations for Hg(II) were(0.14x108),( %-1.1),( %1.42 ) respectively. The above newly synthesized compounds were investigated for their antibacterial. | ||
