摘要：Mn(II), Co(II), Zn(II) and Cd(II) carbonates, respectively, were achieved by a new chemical procedure underthe reaction of aqueous solutions of metal ions (MnCl2, Co(NO3)2, Zn(NO3)2 or CdCl2), potassium iodide and urea withmolar ratio 1:2:10, respectively, at ~ 90 oC for 3 hrs. The infrared spectra of the results indicate absence of the essentialbands of urea, but existed of the characteristic bands of ionic carbonate, CO32–. An important chemical mechanismsdiscussed the preparation of Mn(II), Co(II), Zn(II) and Cd(II) carbonate compounds were suggested.
