Average particle sizes are 50-100 nm.
How can the nanopowder Iron(II,III) oxide, Product 637106, be dispersed in an aqueous solution?
1. It is recommended to use a neutral buffered solution (approximately pH 7). The pH of the solution is an important factor in achieving a monodispersion of the nanopowder.2. Probe-type ultrasonication is strongly recommended by the manufacturer.3. If the material is not well dispersed by ultrasonication in a neutral buffer, add a surfactant. This will wet the nanoparticle surface. Since the particles are small (less than 50 nm), they have a high surface area to volume ratio. They can therefore absorb gases such as oxygen or carbon dioxide from the air, which would decrease the dispersity of the particles. Degassing the buffer before use may help to eliminate the formation of gas bubbles.
