- Abstract:
- The black organic ink powder obtained from the waste toner drum after being treated by the waste toner drum crushing magnetic separation device is used as the raw material. The surface organic matter is removed by environmentally friendly low boiling point organic solvent treatment, and a brown magnetic iron oxide material can be obtained by calcination at 500 ℃. XRD measurement shows that the iron oxide obtained by this method is γ- Fe2O3; Scanning electron microscopy (SEM) shows that its morphology is uniform and circular, with an average particle size of around 200 nm. The gas sensing performance test results show that compared with commercial Fe2O3, this γ- Fe2O3 material has good gas sensitivity and selectivity to VOCs (ethanol, acetone, etc.) gases, and is expected to be applied in the detection of volatile organic compounds
