In this paper, Chitosan/cellulose hybrid particle was prepared and used as absorbent for active red dye. The surface of the particle was observed by using SEM analysis. And the absorption effect was measured. The results show that the surface of the particle is porous and can effectively absorb the dye. The saturated amount reached 9mg/g when the concentration was 40mg/L.The adsorption amount decreases with the increasing of pH value of the dye solution.
