| description | The invention discloses a three-dimensional porous demulsifier for separating an oil-in-water emulsion system and application of the three-dimensional porous demulsifier. The method comprises the following steps: 1) carrying out reflux reaction on graphene oxide and an ethanol solution of tetradecylamine; 2) immersing the polyurethane sponge into an ethanol solution obtained by reaction of graphene oxide and tetradecylamine; and 3) taking out the polyurethane sponge, and drying in a drying oven to obtain the demulsifier. The preparation method is convenient, simple to operate, small in secondary pollution and high in treatment efficiency. The demulsification is realized through an absorption-extrusion process, the method can be used for demulsification and separation of an oil-in-water emulsion system, the defect that demulsification particles cannot be continuously treated is overcome, the problems existing in practical application of an existing demulsification technology can be reduced or eliminated, and t |
