| Abstract: | Preparation of the surface coating chitosan adsorbent from waste mycelium of penicillium chrysogenum was studied,and its adsorption behavior of Ni 2+ was discussed.Results show that the mycelium is better than the peanut hull in the preparation of the surface coating chitosan adsorbent; the adsorptive capacity of Ni 2+ by the surface coated adsorbent increased by 50%,compared with the mycelium adsorbent.The surface coated adsorbent can be reused for 10 times without losing its adsorption capacity.The isotherm of its adsorption behavior accords with Freundhlish and Langmuir models fairly. |
