Preparation and its Cr (VI) adsorption properties of biomimetic FeS composites

  • 摘要: 纳米FeS比表面积大且还原性强,对Cr(VI)吸附性能优异,但不稳定、易团聚,为解决这一问题,本研究以油菜花粉为生物模板,通过共沉淀-焙烧法制得仿生FeS复合材料(bioFeS)。通过SEM、XRD及XPS等方法对bioFeS复合材料的表面微观形态和结构进行了表征。以Cr(VI)为目标污染物,分别考察了吸附剂用量、反应时间、反应温度、初始Cr(VI)浓度和pH对bioFeS复合材料吸附Cr(VI)性能的影响,探究了反应机制。结果表明:油菜花粉生物模板成功分散了FeS,制得的bioFeS复合材料比表面积大,在反应时间为120 min、pH为1、吸附剂投加量为0.2 g·L−1、反应温度为25℃的条件下,bioFeS复合材料对Cr(VI)的吸附量可达88.95 mg·g−1;该吸附过程符合准二级动力学和Langmuir等温吸附模型;共存离子NO3和SO42−会抑制Cr(Ⅵ)的去除。结合吸附动力学、热力学及XPS表面元素分析可知bioFeS复合材料除铬机制主要是吸附及化学还原作用。bioFeS复合材料处理含铬废水具有广阔的应用前景。
