摘要
以氧化石墨烯(GO)和壳聚糖(CS)为原料,采用一步水热法制备了氧化石墨烯/壳聚糖复合气凝胶(GO/CS)。分别研究了制备方法和原料比例对其吸附甲基橙(MO)的影响。结果表明:水热法制得的气凝胶为三维网状结构,且水热法制备的氧化石墨烯/壳聚糖复合气凝胶(GO/CS)较溶胶-凝胶法具有更好的吸附性能,当GO与CS的质量比为10:1时,复合气凝胶对甲基橙去除率最高。
Graphene oxide/chitosan composite aerogel(GO/CS) was prepared by one-step hydrothermal method using graphene oxide(GO) and chitosan(CS) as raw materials. The effects of preparation methods and raw material ratio on the adsorption of methyl orange(MO) were studied. The results show that the aerogel prepared by hydrothermal method is a three-dimensional network structure, and the prepared graphene oxide/chitosan composite aerogel has better adsorption performance than the sol-gel method. When the mass ratio of GO to CS is 10:1, the composite aerogel prepared has the highest removal rate of methyl orange.
