Abstract: The artificial rutile waste liquor contains a large number of iron ions. Due to the strong acidity of waste liquor, its pH is usually less than 1, which leads to high costs of processing and low atomic utilization rate. In this work, PEG-2000 was used as a template, artificial rutile waste liquor and NaOH was used as raw materials. Using simple hydrothermal method to synthesize spherical α-Fe2O3 nanoparticle with complete gra-nularity, and the average particle size was around 200 nm. The product was analysed and characterized by XRD and SEM, the results of XRD showed that synthesized α-Fe2O3 nanoparticle crystal was complete. It was concluded that the addition of PEG-2000 had a significant effect on the particle appearance by observing particle appearance with SEM. The new technology of using the artificial rutile waste liquor to synthesize α-Fe2O3 nanoparticle not only gained α-Fe2O3 nanoparticle with high accessional value, which would make full use of resource, but also reduced the sewage treatment load, which bring guiding significance for industrial production in the future.
