摘要/Abstract

摘要： 采用自组装的方法将多巴胺（DA）与氧化石墨烯（GO）共混制得多巴胺修饰的石墨烯气凝胶（DA-rGA）。利用SEM和FTIR对制备的产品进行了表征，并研究了其对孔雀石绿（MG）、藏红T（ST）和罗丹明B（RhB）的吸附性能。结果表明，制备的DA-rGA具有三维多孔网络结构，其对MG、ST和RhB的最大吸附量分别为735、1 191、348 mg/g，吸附过程符合Langmuir吸附等温式。

关键词: 石墨烯气凝胶, 水热合成, 染料吸附

Abstract: Using self-assembled method,the dopamine-modified reduced graphene aerogels(DA-rGA) has been made by co-mixing dopamine(DA)with graphene oxide(GO),the prepared product characterized by means of SEM and FTIR,and its adsorption capability for malachite green(MG),safranine T(ST) and rhodamine B(RhB) investigated. The results show that the prepared DA-rGA has three-dimensional porous structure. Its maximum adsorption capacities for MG,ST and RhB are 735,1 191,348 mg/g,respectively. The adsorption process complies with Langmuir adsorption isotherm.
