摘　　要：制备了功能化石墨烯,并研究了不同条件下功能化石墨烯对亚甲基蓝的吸附性能.结果表明,电解法是一种制备功能化石墨烯的简单有效方法,其对亚甲基蓝的吸附量可达300 mg/g以上,是普通石墨对亚甲基蓝的吸附量的3倍;并且吸附量随着pH值的增加而递增;在pH为8,温度是20℃时,功能化石墨烯对亚甲基蓝的吸附可在60 min时达到吸附平衡.The functionalized graphene was prepared by electrolyzed the electrolyte.This investigation concerned the adsorption of functionalized graphene towards methylthionine chloride.All results show that the electrolysis method is a simple and effective preparation method.And the adsorption quantity of functionalized graphene on methylthionine chloride can reach more than 300 mg·L-1 and was 3 times than that of graphite.The adsorption quantity will increases along with the acidity increasing,Under the condition of 20 ℃,pH=8,the adsorption was able to reach the adsorption equilibrium within 60 minutes.
