英文摘要：

Preparation of magnetic chitosan immobilized by ionic liquid and the adsorption capacity for acrylamide were studied.Magnetic chitosan was prepared by suspension process using Fe3O4 as magnetic nanoparticles and immobilized by ionic liquid using glutaraldehyde as cross-linker.The adsorption of magnetic chitosan immobilized with ionic liquid toward acrylamide was studied by ultraviolet spectrophotometry.The experiment of adsorption kinetics showed that the adsorption capacity of magnetic chitosan immobilized with ionic liquid toward acrylamide was 1.45 mg·g-1 after shaking for 2 h,and the adsorption reaction reached balance after shaking for 3 h.It indicated that magnetic chitosan immobilized with ionic liquid had good adsorption property toward acrylamide.
