In the present work the thermal decomposition step of some lanthanides and yttrium compounds involving different ligand phenyl-substituted derivatives of benzylidenepyruvate was appraised by thermogravimetry (TG). A correlation about the metal ions content was made by comparision of the results obtained by TG and EDTA complexometry.
