Removal Polyacrylamide from Oil Recovery Wastewater by γ-Fe2O3 Magnetic Particles

Abstract:

Polyacrylamide is of concern in oil recovery wastewater treatment because of its persistence and environment effects. A concept is proposed to synthesize γ-Fe₂O₃ particles with magnetic functionalization for polyacrylamide removal from aqueous media. Magnetic particles were synthesized by the sol-gel method, using NH₄HCO₃ and FeSO₄·7H₂O. These magnetic particles show high adsorption capacity for polyacrylamide. Because of the useful magnetic property, large specific surface area and fast magnetic separation, the synthesized materials will provide a convenient and highly efficient means to remove polyacrylamide from oil recovery wastewater.
