THE STRUCTURE OF NANOCOMPOSITES BASED ON MAGNETITE AND HUMIC ACIDS PRODUCED BY CHEMICAL COPRECIPITATION AND MECHANOCHEMICAL SYNTHESIS
RESUMO
A comparative analysis of methods used for obtaining hybrid functional materials based on magnetite nanoparticles and humic acids by in situ chemical co-deposition or mechanochemical dispersion showed that the method of in situ chemical co-deposition is optimal for producing Fe3O4−HA nanocomposites with reproducible sizes and structure. The possibility of regulating the sizes and magnetic properties of magnetite nanoparticles by varying the Fe3O4 and HAs ratio in the composite is demonstrated. The mechanochemical synthesis method provided opposite results in terms of decrease and increase of particle sizes, which varied in a broad range from nanoscale to micrometer sizes depending on synthesis conditions, accompanied by their increased size distribution. X-ray phase and Mossbauer studies of the hybrid material samples produced by mechanochemical synthesis showed parameters not typical of the magnetite phase.
