Study The Electronic Transition Behavior of Divalent Transition Metal Cations Co (II), Ni(II) and Cu(II) in Aluminum Nitrate/Urea Room Temperature Ionic Liquid (1:1.2)

Divalent transition metal cations of Co (II), Ni (II) and Cu (II), were investigated in new ionic liquid of 11.2 mole ratio of Al (NO3) 3.9H2O/urea and found to be soluble and interacte of with weak coordination bond with ionic liquid species. This was observe when change the strength of the electronic spectra of these cations or the feature of these spectra behavior when compared to those in aqueous solution and their substitution upon addition of thiocyanate. Basic species of ionic liquid were propose to have weak ionic strength.
