- 摘要:
- 对染料的吸附一直都是人们研究、关注的热点。通过水热合成法制备Fe3O4@ZIF-7复合材料,使之作为吸附剂对孔雀石绿溶液进行吸附。通过紫外可见分光光度计测定,以吸附量为评价指标,考察了其对孔雀石绿的吸附能力。采用扫描电镜和能谱分析等手段对Fe3O4@ZIF-7材料进行了表征,确定合成材料为质地均匀、表面多孔的磁性纳米材料。结果表明:当振荡时间是90 min,pH为3,吸附剂用量为4 mg时,Fe3O4@ZIF-7材料对孔雀石绿溶液的吸附效果最好,表明其对该溶液有良好的吸附效果。
- Abstract:
- Adsorption of dyes has always been a research hotspot. In this experiment, Fe3O4@ZIF-7 composite material was prepared by a hydrothermal synthesis method and adsorbed malachite green solution as an adsorbent. The adsorption amount was used as an evaluation index to measure with a UV-visible spectrophotometer to investigate its ability to adsorb malachite green. Then this material was characterized by scanning electron microscopy and energy spectrum analysis. The results showed that the synthetic material was a magnetic nanomaterial with uniform texture and porous surface. And the material Fe3O4@ZIF-7 had the best adsorption effect on the solution when the shaking time was 90 min, the pH was 3, and the amount of adsorbent was 4 mg. Therefore, Fe3O4@ZIF-7 nanocomposite had good adsorption performance for malachite green solution.
