Abstract:SYNTHESIS, CHARACTERIZATION OF A CHITOSAN SCHIFF BASE AND COPPER COMPLEXES USED AS A MODIFIED ELECTRODE. A new material formed by Shiff base (chitosan and ortho-vanillin) and copper were synthesized and characterized by UV-visible, infrared spectroscopies, thermal analysis, elemental analysis, electron microscopy, 1H NMR spectra and electrochemical techniques. In this study, it was possible to identify the formation of Schiff’s base (BS), with a degree of substitution of 42.5% by NMR. The electron microscopy s… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
