  • Chitosan-polyvinyl alcohol composite hydrogel was prepared using the hydrothermal method and scanning electron microscope (SEM)was used to detect the surface morphology of the composite hydrogel.Then the adsorption ability was detected through static adsorption experiments and desorption tests in water solution and soil digestion solution,respectively.Results suggested that the chitosan-polyvinyl alcohol composite hydrogel,as material with large surface area and more pores 10~60 μm in diameter, could effectively remove arsenic from both wastewater and soil.The adsorbing capacity were 3.976 mg arsenic/g hydrogel and 3.480 mg arsenic/g hydrogel,respectively.The desorption efficiency of this composite hydrogel to arsenic was higher,and the hydrogel could be reused.The desorption efficiency were 74.7%~81.4% and 64.1%~77.0%,respectively for wastewater and soil.So the chitosan/polyvinyl alcohol composite hydrogel could effectively remove arsenic from both wastewater and soil.
