Method for adsorbing polystyrene microplastics in water by adopting three-dimensional graphene

The invention provides a method for adsorbing polystyrene microplastics in water by adopting three-dimensional graphene. According to the invention, the polystyrene microplastics are taken as a targetobject, three-dimensional reduced graphene oxide is taken as an adsorbent, and the three-dimensional reduced graphene oxide after freeze drying forms a three-dimensional porous structure, so that more adsorption sites can be provided for the target object. The method adopts a very small amount of the three-dimensional reduced graphene oxide to adsorb the polystyrene microplastics, and the adsorption effect is very considerable in a short time. The feasibility and application prospect of the three-dimensional graphene as an adsorption material in the treatment of microplastics pollution in thewater are verified, and a new idea is provided for the treatment of the microplastics in the water. 本发明提供了一种采用三维石墨烯吸附水中聚苯乙烯微塑料的方法。本发明以聚苯乙烯微塑料为目标物，三维还原氧化石墨烯为吸附剂，经过冷冻干燥后的三维还原氧化石墨烯形成了立体的多孔结构，可为目标物提供较多的吸附位点。本发明的方法采用极少量的三维还原氧化石墨烯对
