摘要：
In this study,the chitosan(CS) -iron(II, III) oxide magnetic microspheres were prepared by crosslinking and coprecipitating with carbamide solution as precipitated agent.,and characterized by means of scanning electron microscope(SEM) and Fourier Transform infrared spectroscopy (FTIR). The adsorption performance of the magnetic microspheres for remove Cr(VI) from aqueous solution was investigated. The experimental results demonstrated that the optimum of pH,time for adsorption of Cr(VI) was 3.3,120min at 25 degrees C, respectly.
