Synthesis and Characterization of EDTA Complexes Useful for Trace Elements Supplementation

We began, in this work, by the synthesis of the Cu(II) complex with DL-a-alanine which is characterized by powder X-ray diffraction, the UV-visible spectroscopy and the infrared spectroscopy. The RXs show that the complex has the formula C 6 H 12 N 2 O 4 Cu, 2H 2 O while the experimental data show that the ligand is bidentate and the studied complex adopts octahedral stereochemistry. We then studied the inhibitory effect of Bis (DL-a-alaninato) copper dihydrate complex on ordinary steel in 1M HCl solution. The corrosion inhibition study of this complex was carried out by the electrochemical method (stationary and transient). The measurements carried out by this method gave a maximum efficiency of 88% to 10 -5 M of Bis (DL-a-alaninato) copper dihydrate complex on an ordinary steel surface of 1 to 2 cm dimension in the presence of a 1M HCl solution. The obtained results show that the adsorption process of the Bis (DL-a-alaninato) copper dihydrate complex on the metal surface obeys the Langmuir adsorption isotherm.

“…The concentration of PTP1B was 60 nm, with fixed substrate concentration of 2.0 mM and the concentrations of oxovanadium complex (II) ranging between 1 nM and 10 mM.3. Results and discussionNIR spectra of all complexes in the 650-150 cm −1 region were measured and assigned according to data of analogous complexes found in the literature[16,[40][41][42][43]. The Cd-N frequencies were assigned to 431 and 456 cm −1 , respectively (aliphatic N atoms), and 278 cm −1 (N from benzimidazole); the Cd-O stretching frequency to 226 cm −1 .…”

“…Although cyclic voltammogram is similar to the electrochemical response of AgNPs electrodeposition with cyanide, in this case, the reduction peak is located at positive potentials (+0.28 V, green segment in Figure 5a) instead of at negative values. Raman spectra of Ag-EDTA complex show several bands related to different vibration modes, [61] showing all of them similar behavior with potential. Band centered at 710 cm −1 is selected as representative band of Ag-EDTA complex due to its higher Raman intensity during AgNPs generation.…”

Chemical and physical properties of metal nanoparticles (NPs) are determined not only by the synthesis method used to prepare them but also by the experimental conditions under the generation process takes place. One of the most important factors in the synthesis of NPs is the presence of complexing agents in the media that can change the size and shape of the NPs. The significant role of different complexing agents (cyanide, ethylenediaminetetraacetic acid, and ethylenediamine) in the electrochemical formation of silver nanoparticles (AgNPs) has been analyzed by time‐resolved Raman spectroelectrochemistry. Electrochemical and spectroscopic responses, obtained simultaneously, provide suitable information about the changes that occur on the platinum electrode surface during the AgNPs electrodeposition. The morphology of AgNPs has been analyzed by ultraviolet–visible absorption spectroelectrochemistry, providing additional information and a detailed view of the electrodeposition process. The influence of the complexing agent used to generate AgNPs has been studied analyzing the surface‐enhanced Raman scattering (SERS) effect of the modified substrate. Raman spectra show different SERS behavior depending on the complexing agent and therefore on the AgNPs generated. The relationship between SERS signals and the morphology of AgNPs has been displayed by scanning electron microscopy images. Time‐resolved Raman spectroelectrochemistry confirms that chemical mechanism is necessary for SERS effect.
