Abstract: Amoxicillin functionalised ferrite nanoparticle was synthesised by co-precipitation method under nitrogen atmosphere. Thus obtained black coloured product was characterised by Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, X-ray diffraction (XRD), particle size analysis (PSA), scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM) and vibrating sample measurement (VSM) techniques. The sedimentation velocity of starch in the presence of amoxicillin functionalised ferrite was carried out at three different pH values namely 2.5, 7.1 and 12.0. The influence of amoxicillin functionalised ferrite on the sedimentation velocity of starch was evaluated with the help of FTIR, SEM, VSM, UV-visible, fluorescence spectroscopy. We noted an important observation that Starch-Fe₃O₄-amoxicillin system exhibited the lowest VSM value than the Fe₃O₄-amoxicillin system.
