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.

通过一步合成制备磁性纳米粒子，根据反应时间和温度处理改变粒子的形态

摘要

在目前的研究中，通过在高达60°C的温度下，通过与氢氧化钠溶液反应的Mohric盐（NH ₄）₂ Fe（SO ₄）₂ ·6H ₂ O容易地一步沉淀来合成纳米级的氧化铁颗粒。当改变反应时间时，制备了不同形状的氧化铁颗粒，并且当在60℃的高温下干燥湿提取的颗粒时，观察到了二维形状的变化。根据反应时间的不同，本研究中获得了不同比例的FeOOH和Fe ₃ O ₄。本研究使用DTA – TGA，XRD，FTIR和SEM表征颗粒。
