- Abstract
Condensation of Ethyl 2-methylacetoacetate and ethylenediamine yield 88.7% of 5,12-Dimethyl-7,14-Diphenyl-1,4,8,11 -Tetraazacyclo tetradeca-4,7,11,14-Tetraene with a condense chemical formula as C18H32N4O2, and a molecular weight of 336.47. The complexes were prepared by the adsorption of heavy metals (Fe, Cu, Cd, Co and, Pb) from wastewater samples obtained from Kofar sauri, Lambun Dan Lawal and Youth craft village. The compounds were investigated by solubility, conductivity, melting/decomposition point, Atomic Absorption Spectroscopy, Infrared spectroscopy and Uv-visible spectroscopy. The Ligand 003 shows IR peak of u(C=N) at 1633cm-1, and a shift was observed to a lower peak as a result of adsorption of the heavy metals by the ligand, which is signifying the formation of the complexes. AAS results indicates high concentration of Cu in each case when compared, the rest of the metals varying at different leve l of concentration in the compounds. Cu may best fit the center of the ligand cavity having a concentration beyond computing with the rest of the metals.
