Infrared spectroscopic investigation on the reaction mechanisms of urea with manganese(II), cadmium(II), magnesium(II) and calcium(II) formate at elevated temperature

Abstract

The manganese(II), cadmium(II), magnesium(II) and calcium(II) carbonates, respectively, were achieved by a novel synthetic route through the reaction of aqueous solutions of Mn(HCOO)2.xH2O, Cd(HCOO)2, Mg(HCOO)2.2H2O, or Ca(HCOO)2 with a low cost precursor like urea at ~ 85 oC for 12 hrs. The infrared spectra of the results indicate absence of the individual bands of urea, but exhibited of the characteristic bands of ionic carbonate, CO3 2–. A general reaction mechanisms describing the preparation of Mn(II), Cd(II), Mg(II) and Ca(II) carbonate compounds were discussed.
