Marine spilled-oil gelling agents based on supramolecular self assembly and preparation method of spilled-oil gelling agents

The invention belongs to the technical field of chemical applications, and in particular relates to preparation of novel marine spilled-oil gelling agents based on supramolecular self assembly and anapplication of the spilled-oil gelling agents in the treatment of oil-containing wastewater. The oil gelling agents are subjected to self assembly in a solvent to form a three-dimensional net-shaped structure to adsorb oil, so that the solvent is immobilized to make the whole network system gel, and the gel can be completely separated from an aqueous phase through salvage. The oil gelling agents are easy to synthesize, have low costs, can be widely applied to different oil including crude oil, can efficiently and quickly immobilize the oil, and can be applied to the oil-containing wastewater while the gelation ability is not affected by other substances in an aqueous phase, such as heavy metals and inorganic salts, so that the gel is separated from the aqueous phase, secondary pollution towater does not exist, and
