Abstract:

In polysorbate 80 - alcohol system, Cr2O3 powder had been prepared by using chromium-containing waste liquid from 16-dehydropregnenolone acetate. A precipitation was obtained when water was separated from the wastewater. The nanosample was got after the precipitation was calcined at 250 °C and 600 °C. Cr2O3 powder structure was characterized by FT-IR, SEM and XRD. The results show that the powders are spherical hexagonal system Cr2O3 nanoparticles. The particles size prepared in polysorbate 80 and n-Amyl alcohol system are 50-95 nm. The average value is 78 nm.
