摘要:
采用表面负载法制得聚乙烯亚胺/四氧化三铁吸附剂(PEI@Fe3O4)，以刚果红(Congo Red, CR)为吸附质，系统考察吸附剂用量、pH值、吸附时间和染料初始浓度等因素对吸附材料性能的影响。结果表明，CR在PEI@Fe3O4上的吸附受离子强度影响很大且利于吸附过程；303 KCR的最大吸附量为58.3 mg/g，等温吸附过程符合Redlich-Peterson方程且吸附过程符合Elovich动力学模型。解吸再生实验表明，吸附剂多次吸附/解吸附循环仍可维持吸附性能，显示出良好化学稳定性。因此，该吸附剂在染料废水CR去除方面具有良好应用前景。
Abstract:
Polyethylenimine@Fe3O4 magnetic composites (PEI@Fe3O4) were prepared by a surface overlay method and characterized. Its adsorption property toward Congo red (CR) from solution was performed in batch mode. The results showed that it was favor of CR adsorption onto PEI@Fe3O4 with the increase of ionic strength. Adsorption isotherms from experimental results were fitted well by Redlich-Peterson model and the adsorption quantity from experiment was up to 58.3 mg/g at 303 K. The kinetic process was best predicted by the Elovich model. Desorption and regeneration experiments showed that the adsorbent can retain its adsorption capacity even after adsorption/desorption cycles, showing excellent mechanical and chemical stabilities. It was implied that PEI@Fe3O4 be promising in removal of anionic dyes from wastewater
