| 摘 要： | 采用铁盐对废弃蛋壳进行化学改性,并研究改性蛋壳对水中磷的吸附特征.结果表明,改性蛋壳明显提高磷的吸附能力,磷在改性蛋壳中的吸附是一吸热过程,其吸附等温线符合Freundlich方程,磷在改性蛋壳中的吸附历时曲线遵循准二级反应动力学模型.溶液pH值显著影响磷在改性蛋壳中的吸附效果,当pH3时,改性蛋壳对磷具有吸附最大值.

| Abstract: | Modification of wasted eggshell using ferric salt and phosphorus adsorption behaviors on the iron-coated eggshell are investigated.The results show that phosphorus adsorption capacity can be markedly improved on iron-coated eggshell compared to that on eggshell without modification.Phosphorus adsorption on iron-coated eggshell is an endothermal process,and its adsorption isotherms can be well described by Freundlich equation.The time-resolved curves of phosphorus adsorption on iron-coated eggshell follows p... |
