Dicyanamide Ions as Complexing Agents of Co(II): From Weak Ligands in Water to Strong Ones in an Ionic Liquid
2018
Solvent extraction and ion exchange
The complexation of cobalt cations (Co(II)) by dicyanamide (DCA -) in water and 1-butyl-1- has been investigated by recording UV-vis spectra at 20 °C for solutions containing different ratios for the concentrations of DCAvs. Co(II) (R = [DCA -]/[Co(II)]). The variation of the absorbance at a fixed wavelength as a function of R was expressed using the Beer Lambert law, based on a chemical model assuming the formation of up to four successive cobalt-dicyanamide complexes. This allowed us to
