摘要：AbstractHybrid coagulant/flocculant consisting of nanomaterials have tremendous potential in solid‐liquid separation and can be applied to the coagulation‐flocculation‐sedimentation process of water treatment. In this work, inspired by the mineralization in nature, a graphene oxide/polymer‐based hybrid coagulant/flocculant that precipitates large‐scale, multicomponent (e.g., dyes, heavy metal ions, and nanoparticles) and complex pollutants simultaneously at room temperature by forming double‐network hydrogel through bioinspired Ca2+crosslinking, is developed for the purification of wastewater. The coagulation‐flocculation‐sedimentation method developed here also provides a novel strategy for the preparation of macroscopic assemblies of multicomponents that can be applied to various application fields.This work demonstrates a graphene oxide/polymer‐based hybrid coagulant/flocculant, precipitating large‐scale, multicomponent (e.g., dyes, heavy metal ions, and nanoparticles) and complex pollutants simultaneously at room temperature by forming a double‐network hydrogel through Ca2+crosslinking to achieve the purification of wastewater.
