The purpose of this project is to synthesise and characterize iron from clay ore which would be used in biomedical applications. Two sources of clay samples were obtained from the Savannah and Volta Region for the studies. The clay sample from the Savannah Region revealed a milky colour, while the clay sample from the Volta Region had red colour. The as-received clay was characterized with X-ray fluorescent (XRF) spectroscopy to determine the major oxides and elemental compositions. The results from the XRF studies shows that, the Savannah and the Volta clays contains 10.2 mass%, and 8.49 mass% hematite (Fe2O3). Iron synthesis was achieved via chemical leaching with phosphoric acid, and hydrochloric acid. The leached substance was analysed with ultraviolet visible (UV-Vis) spectroscopy. Kinetics of iron released was analysed using kinetic modules such as Zeroth order, First order, Second order, and Higuchi model. The results agreed with the Zeroth and Second model with a linear fit and regression coefficient, R2 = 0.994 and R2 = 0.998 respectively. The iron in solution was precipitated from solution using sodium hydroxide to enhance the yield of the iron. The implications of the results were discussed for the synthesis and further characterization of conjugated iron nanoparticles for biomedical applications.
