Summary: | STRUCTURAL CHARACTERIZATION OF THE PANI-MAGNETITE COMPOSITE WITH POTENTIAL APPLICABILITY IN ELECTROCHEMICAL SESNOR. This study presents the production of a composite formed between polyaniline and magnetite (Pani-Mag) through an easy and more economical synthetic route, which satisfactorily contemplates the principles of green chemistry. The production of new materials for technological application also needs to be focused on less waste generation, and greater sustainability. FTIR and DRX analyzes confirm that the interactions between the polymeric phases and the oxide particles occurred in a synergistic way. Saturation magnetization has a value of 33.5 emu g-1, being compatible with reference values in the literature for Pani-Mag composites. The electrochemical tests indicate an electrochemically stable material with the potential to be applied as an electrochemical sensor in the determination of ascorbic acid in solution. |
