[HTML][HTML] Thermal decomposition characterization and kinetics of copper, iron, manganese and zinc chelates of ethylenediaminetetraacetic acid in air atmosphere
M Biegun, M Kaniewski, E Klem-Marciniak… - Thermochimica …, 2022 - Elsevier
The analysis of the thermal stability of Cu, Fe, Mn, and Zn-EDTA (copper, iron manganese,
and zinc chelates of ethylenediaminetetraacetic acid) chelates indicates a high complexity of
occurring decomposition processes, ranging from two to three simplified stages of the
decomposition process. Obtained results reports that the thermal stability decreased in the
following order: Zn-EDTA> Mn-EDTA> Cu-EDTA> Fe-EDTA. The initial model-free kinetic
analysis suggested that three out of four chelates had a multi-step first stage of the …
