摘要：

Solid state chelates of general formula H[Ln(EDTA)] . nH2O (Ln = trivalent lanthanide (except for promethium) or yttrium; EDTA = ethylenediaminetetraacetate) were prepared. Thermogravimetry, differential thermal analysis, X-rav diffraction and complexometry were used to characterize and study the thermal stability and thermal decomposition of these compounds.
