Effect of drying temperature on sizes and morphology of goethite nanoparticles

The morphology, structure, and size distribution of goethite nanoparticles, which are obtained by chemical precipitation of iron salt and alkali in aqueous solutions with different surfactants and are dried at 100°C and room temperature, have been investigated in order to develop technology for obta...

Description
Summary:The morphology, structure, and size distribution of goethite nanoparticles, which are obtained by chemical precipitation of iron salt and alkali in aqueous solutions with different surfactants and are dried at 100°C and room temperature, have been investigated in order to develop technology for obtaining goethite (α-FeOOH) nanoparticles of minimum sizes. It is found that the samples dried at a temperature of 100°C have a different phase state and increased sizes as compared to the samples dried at room temperature.
