摘要
将目前在重金属离子吸附处理方面最具研究价值的两种吸附材料,石墨烯材料和壳聚糖有机结合,制得一种新型复合吸附材料——功能化氧化石墨烯(E-GO)/壳聚糖(CS)复合材料(EGC),考察了EGC对Cr(Ⅲ)的吸附性能。实验表明,EGC对Cr(Ⅲ)具有优秀的吸附能力,且重复使用性能良好,既克服了石墨烯材料易于团聚、不易回收和壳聚糖机械强度差的缺点,又充分发挥了石墨烯材料吸附容量大和壳聚糖螯合能力优秀的优点,实现了两种吸附材料的优势互补,对于处理含铬废水具有较高的参考和指导意义。
The new composite adsorbent material,functionalized graphene oxide/chitosan composites(EGC),was prepared by organic combination of graphene material and chitosan which had the most research value in the adsorption treatment of heavy metal ions at present.The adsorption property for Cr(Ⅲ)of the EGC was investigated,experiment indicated that the adsorption property for Cr(Ⅲ)and reusability of the EGC was excellent.It not only avoided the properties of easy agglomeration,poor recovery in graphene and low mechanical strength in chitosan,but took full advantage of the great adsorption capacity of graphene and the excellent chelation ability of chitosan.EGC perfectly accomplished complementary advantages in graphene and chitosan,making it a significant material when in came to chromium-containing wastewater disposal.
