Abstract: | Solid-state M-EDTA chelates, where M represents the divalent ions Mg(II), Ca(II), Sr(II) or Ba(II) and EDTA is ethylenediaminetetraacetate
anion, were synthesized. Thermogravimetry, derivative thermogravimetry (TG, DTG), differential scanning calorimetry (DSC)
and X-ray diffraction powder patterns have been used to characterize and to study the thermal behaviour of these chelates.
The results provided information concerning the stoichiometry, crystallinity, thermal stability and thermal decomposition.
