Uv-vis spectrophotometry is still an important instrumental method for the determination of heavy metal ions in
their inorganic or organic complexes.8-15
Various spectrophotometric methods have been proposed for the determination
of copper contents of the various samples including natural
waters and pharmaceutical samples.16-30
Chloro(phenyl) glyoxime is selected as a ligand for copper(II) ions for the present work. The chloro(phenyl) glyoxime and the electrical
properties of its Co(II), Ni(II) and Cu(II) chelates in solid
