摘要
总结了镧改性生物炭的常用制备方法,根据实验及实际应用情况着重介绍了浸渍法和共沉淀法并比较不同制备方法的优缺点;从静电作用、离子交换、络合作用等方面阐明了镧改性生物炭对环境污染物的吸附机制;指出了镧改性生物炭材料在实际应用中可能存在的问题和未来发展方向。
The common preparation methods for lanthanum-modified biochar are summarized,the advantages and disadvantages of different preparation methods are compared,and the impregnation and co-precipitation methods are described emphatically according to the experiments and practical applications.The adsorption mechanism of lanthanummodified biochar for environmental pollutants is clarified in terms of electrostatic effect,ion exchange,complexation,etc.The problems that may exist in the practical application of lanthanum-modified biochar and the development direction in the future are also pointed out.
