Abstract
This work has been carried out to investigate the preparation of EDTA (Ethylenediaminetetraaceticacid) and, DTPA (Diethylenetriaminepentaaceticacid) complexes with some transition metals which used as micronutrient fertilizers.
The composition as well as structural characteristics of various complexes were determined by means of chemical and thermal analyses, electronic absorption, infrared spectra, mass spectra and electron spin resonance.
The results showed that the different complexes can be prepared
