摘要：
Polyacrylamide is of concern in oil recovery wastewater treatment because of its persistence and environment effects. A concept is proposed to synthesize gamma-Fe2O3 particles with magnetic functionalization for polyacrylamide removal from aqueous media. Magnetic particles were synthesized by the sol-gel method, using NH4HCO3 and FeSO4 center dot 7H(2)O. 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.
