The complexes of two chelating agents, CDTA (trans-1,2-cyclohexanediaminetetraacetic acid) and EDTA (ethylenediaminetetraacetic acid), with Ni(II), Co(II) and Cu(II) are studied by means of X-ray photoelectron spectroscopy (XPS). The N1s spectrum of CDTA has two components at 398.5 (+/-0.2 eV) and 400.9 (+/-0.2 eV) while only one signal is found after coordination at 400.0+/-0.2 eV. EDTA shows a N1s spectrum with one component at 400.9+/-0.2 eV. A negative shift of about -1.3 eV is observed in its complexes. The results are compared with the literature data on the complexes in the solid state.

Abstract
The complexes of two chelating agents, CDTA (trans-1,2-cyclohexanediaminetetraacetic acid) and EDTA (ethylenediaminetetraacetic acid), with Ni(II), Co(II) and Cu(II) are studied by means of X-ray photoelectron spectroscopy (XPS). The N1s spectrum of CDTA has two components at 398.5 (+/-0.2 eV) and 400.9 (+/-0.2 eV) while only one signal is found after coordination at 400.0+/-0.2 eV. EDTA shows a N1s spectrum with one component at 400.9+/-0.2 eV. A negative shift of about -1.3 eV is observed in its complexes. The results are compared with the literature data on the complexes in the solid state.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
