摘要
[目的]研究复合材料对染料的吸附性能.[方法]以改进Hummer法制备氧化石墨烯,通过动态界面聚合工艺制备聚苯胺-氧化石墨烯复合材料,并对模拟环境中不同污染性染料进行吸附性能研究.[结果]聚苯胺-氧化石墨烯能显著提高染料的吸附容量和吸附效率,当聚苯胺-氧化石墨烯的用量为1.2 g/L,溶液pH为4,吸附时间为50 min时,对铬黑T的吸附率可达94.04%.相同条件下,复合后的材料吸附性能提高了15%.3种不同染料中,对甲基橙的吸附效果最好.[结论]聚苯胺-氧化石墨烯可用作污水中染料的吸附剂.
Abstract
[Objective]The adsorption properties of composite materials to dyes were studied.[Method]Graphene oxide(GO) was prepared by modified Hummers method and PANI-GO composites was obtained by dynamic interface polymerization process.The adsorption properties of different contaminating dyes in wasrewater were studied.[Result]The experimental results showed that the addition of GO can significantly improve the adsorption capacity and efficiency of complex to dye.The optimal adsorption conditions were the amount of adsorption regents 1.2 g/L, pH 4 and dsorption time 50 min,the removal rate of chrome black T in water reached 94.04%.Under the same conditions, the adsorption performance of composite material was increased by 15%.Among three different dyes, the adsorption effect on methyl orange was the best.[Conclusion]The composite material can be used for the adsorption of dyes in wastewater.
