【 摘 要 】

Wasted Eggshell is modified by FeCl3. The influence of mass concentration of FeCl3 in different situations, reaction temperature and initial concentration of phosphorus on the adsorption effect was studied, the adsorption kinetics, thermodynamic and adsorption isotherm model are used to simulate the process. The results shows that: The adsorption rate of original eggshell is 33%.under the condition of 0.3% FeCl3, 40°C reaction temperature, and 50 mg/L phosphorus, and the adsorption capacity reaches Phosphorus adsorption rate of FeCl3-coated is 99.13%, and the adsorption capacity reaches 3.95mg/g, which is reaching the national two grade effluent standard. The adsorption model fitting results shows that the adsorption of phosphorus on modified eggshells was a physical process of spontaneous, endothermic and anisotropy, and the adsorption rate was affected by the internal pore size.
