摘要:
利用废旧硒鼓经过废旧硒鼓破碎磁选装置处理得到的黑色有机墨粉作为原料,采用环境友好的低沸点有机溶剂处理除去表面有机物,通过500℃煅烧处理即可得到棕褐色的磁性氧化铁材料.经XRD测定发现,该方法处理得到的氧化铁为γ-Fe2O3;扫描电镜SEM显示,其形貌为均匀的圆颗粒状,平均粒径在200 nm左右.气敏性能测试结果表明,与商业Fe2O3相比,这种γ-Fe2O3材料对VOCs(乙醇、丙酮等)气体有较好的气敏响应和选择性,有望在挥发性有机化合物气体检测方面取得应用.
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
