Abstract:A new complex of Zn(II) and 5-Bromosalicylaldehyde thiosemicarbazone (5-BSAT) has been studied. In solution, the 5-BSAT reacts with Zn(II) to form a complex with the maximum absorbance at 381 nm. Zn(II) ion forms a 1:1 stoichiometric complex. The stability constant is 4.21x10 5 . The formation of the complex was completed within 20 min at pH 6.8 and VDMF = 2 mL. Beer's law is obeyed over the range from 0.13 mg. L -1 to 0.39 mg. L -1 Zn (II) and the apparent molar absorptivity (ε) is 1.08×10 4 L.mol −1 .cm −1 .… Show more
