The colorimetric determination of Cu(II) ion by using the polydentate schiff base ligands Bis-(salicylaldehyde)-diethylentriamine(BSDT), Bis- ( salicylaldehyde) -triethylenetetramine (BSTT), and Bis-(salicylaldehyde)-tetraethylenepentamine(BSTP) have been developed. The schiff bases and their Cu(II) complexes were obeyed to Beer's law in the concentration range 1.0X 10-3-4.OX 10 3M. The molar extinction coefficients of the Cu(II) complexes are low, and therefore the sensitivity is relatively low. Cu(ID was determined in the presence of univalent ions and bivalence cation ions but oxlate, EDTA, Fe(II), Fe(III) and Co(II) were interfered.
