Magnetic oxide nanoparticles were prepared by combining magnetic microspheres with pectin and cellulose, which was characterized by IR,TG/DTA,XRD and SEM.The effects of absorption conditions,such as the adsorbent dosage, adsorption time,initial concentration of Cu2+ and pH value of the solution,were systemically investigated.The results showed that the best adsorption quantity was 49.96 mg/g when the effective adsorption time of composite magnetic microspheres was 1.0 h, the dosage was 50 mg,the initial copper ion concentration was 100 μg/ml,and the best pH of the solution was about 3.40.
