摘要
简述了污泥基生物炭制备方法和吸附重金属的影响因素以及主要机理,包括物理吸附、静电吸附、离子交换、络合作用以及化学沉淀;介绍了污泥基生物炭改性方法以提高吸附重金属效果;最后对污泥基生物炭的应用进行了展望。
The preparation methods for sludge-based biochar are reviewed.The influencing factors for adsorption of heavy metals by sludge-based biochar are expounded,and main mechanisms,including physical adsorption,electrostatic adsorption,ion exchange,complexation and chemical precipitation,are briefly described.Meanwhile,the modification methods for sludge-based biochar are introduced to improve its adsorption effect to heavy metals,and finally the application of sludge-based biochar is prospected.
