The reactions of Schiff base ligands, prepd. by the condensation of 4-amino- 5-(3-bromo phenyl)-4H-1,2,4-triazole-3-thiolwith aromatic aldehyde like 4- methoxy benzaldehyde was studied with Cu(II), This complex was characterized from IR, 1HNMR and spectrophotometric analysis. A photometric method for the determination ofCu(II) of its 5-(3-bromo phenyl)-4-{[(1E)-(4- methoxy phenyl)methelene]amino}-4H-1,2,4-triazole-3-thiol (SB1) complex is described. The insoluble colored complex of Cu(II) was extracted in chloroformand the absorbance ismeasured at 410 nm. BeerÂ’s lawis obeyed up to 30.48 ppmfor Cu(II) complex. The interference of diverse ions has also been investigated.
