Preparation of magnetic nanoparticles by one step synthesis with morphology of particles changed based on time of reaction and temperature treatment
Source abstract
Abstract
In present study, nanosized iron oxides particles are synthetised by easy one step precipitation from Mohric salt (NH4)2Fe(SO4)2·6H2O reacting with sodium hydroxide solution in temperature up to 60 °C. When changing the time of reaction, the iron oxide particles of different shape are prepared and when drying wet extracted particles at elevated temperature of 60 °C the change of 2D shaped morphology is observed. Depending on the time of reaction different ratios of FeOOH and Fe3O4 are obtained in this study. DTA – TGA, XRD, FTIR and SEM are used for the characterisation of particles in this study.
