| Abstract | A pencil lead electrode coupling with nano-magnetite adsorption as pre-concentration and extraction in order toanalyze salicylic acid (SA) was demonstrated in this work. The optimum conditions for nano-magnetite (Fe3O4)preparation by co-precipitation of ferrous/ferric ions were studied. The parameters affecting the shape and size of thenano-magnetite particles such as the types of base, addition rate, temperature, stirring rate and pH were optimized.The morphology was characterized by Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopyand transmission electron microscopy. The application of nano-magnetite as the solid phase extractor for the squarewavevoltammetry (SWV) of SA gave good results. |
