The current water crisis necessitates the development of new materials for wastewater treatment. A variety of nanomaterials are continuously being investigated for their potential as adsorbents for environmental remediation. Researchers intend to develop a low-cost, simple, and sustainable material that can cater to removal of pollutants. Biochar derived from biowaste is a potential candidate for the existing problem of water pollution. The review focuses on the various aspects of biochar, such as its sources, preparation methods, mechanism, applications for wastewater treatment, and its regeneration. Compared with other adsorbents, biochar is considered as an environmentally friendly, sustainable, and cost-effective substitute for waste management, climate protection, soil improvement, wastewater treatment, etc. The special properties of biochar such as porosity, surface area, surface charge, and functional groups can be easily modified by various chemical methods, resulting in improved adsorption properties. Therefore, in view of the increasing environmental pollution and the problems encountered by researchers in treating pollutants, biochar is of great importance. This review also highlights the challenges and prospective areas that can be explored and studied in more detail in the future.
当前的水危机使得开发用于废水处理的新材料成为必要。人们不断研究各种纳米材料作为环境修复吸附剂的潜力。研究人员打算开发一种低成本、简单且可持续的材料，以满足去除污染物的需求。源自生物废料的生物炭是解决现有水污染问题的一个潜在选择。这篇综述聚焦于生物炭的各个方面，例如其来源、制备方法、作用机制、在废水处理中的应用以及再生。与其他吸附剂相比，生物炭被认为是一种环境友好、可持续且具有成本效益的替代品，可用于废物管理、气候保护、土壤改良、废水处理等。生物炭的特殊性质，如孔隙率、表面积、表面电荷和官能团等，可通过各种化学方法轻松改性，从而提高吸附性能。因此，鉴于环境污染日益严重以及研究人员在处理污染物时遇到的问题，生物炭具有重要意义。本综述还强调了未来可更详细探索和研究的挑战及潜在领域。
