Abstract:
PURPOSE: Are provided an adsorption sequestrant of anionic surfactant and the elimination method of anionic surfactant by using the same, which can eliminate the anionic surfactant from waste water by absorption-elimination ability of magnetite, can recovery easily absorbent by magnetism of magnetite and can reuse the recovered magnetite to activate the magnetite. CONSTITUTION: The adsorption sequestrant of anionic surfactant contains magnetite(Fe3O4) as main component. The elimination method of anionic surfactant is comprises; adsorption eliminate anionic surfactant by adding magnetite in aqueous contained anionic surfactant; recovery the magnetite adsorbed surfactant by using permanent magnetic or electromagnet; reactivating recovered magnetite by heating at 300-500°C; and reusing the magnetite as adsorption sequestrant.
