The reaction between copper(II) and chromium(III)-DTPA complex has been investigated in aqueous solution by potentiometric and UV-vis spectrophotometric measurements. Copper (II) forms mononuclear complex species, as well as mixed complexes with hydrogen and hydroxide ions, the stability constants of which have been calculated at 20-degrees-C in 1.0 mol dm-3 (Na,H)ClO4. A solid species has also been prepared and analysed by IR spectroscopy and thermal measurements.

Abstract
The reaction between copper(II) and chromium(III)-DTPA complex has been investigated in aqueous solution by potentiometric and UV-vis spectrophotometric measurements. Copper (II) forms mononuclear complex species, as well as mixed complexes with hydrogen and hydroxide ions, the stability constants of which have been calculated at 20-degrees-C in 1.0 mol dm-3 (Na,H)ClO4. A solid species has also been prepared and analysed by IR spectroscopy and thermal measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
