New chemical procedures for preparation of manganese(II), cobalt(II), zinc(II) and cadmium(II) carbonates under the catalytic behavior of metal ions: Discussion of infrared spectral bands

Abstract

Mn(II), Co(II), Zn(II) and Cd(II) carbonates, respectively, were achieved by a new chemical procedure under the reaction of aqueous solutions of metal ions (MnCl2, Co(NO3)2, Zn(NO3)2 or CdCl2), potassium iodide and urea with molar ratio 1:2:10, respectively, at ~ 90 oC for 3 hrs. The infrared spectra of the results indicate absence of the essential bands of urea, but existed of the characteristic bands of ionic carbonate, CO3 2–. An important chemical mechanisms discussed the preparation of Mn(II), Co(II), Zn(II) and Cd(II) carbonate compounds were suggested.
