摘要
综述了生物炭的一些改性方法,主要包括磁技术改性、杂原子掺杂改性、球磨改性、酸碱改性,重点总结了这些改性生物炭在吸附抗生素方面的应用.废水中的抗生素对环境的影响日益严重,生物炭作为一种高效、低成本的吸附剂,具有吸附抗生素的潜力.还分析了改性生物炭对废水中抗生素的去除机理,主要包括静电相互作用、H键、π-π相互作用、表面络合.总结了目前改性生物炭的一些不足和对未来工作提出了相应的展望,以期改性生物炭可以更好的用于废水中抗生素的处理,在环境修复方面发挥更大的作用.
Abstract
This paper reviews some modification methods of biochar,including magnetic modification,het-eroatom doping modification,ball milling modification,acid-base modification,and focuses on the applica-tion of these modified biochar in the adsorption of antibiotics.Biochar,as an efficient and low-cost adsor-bent,has the potential to adsorb antibiotics because of the increasing environmental impact of antibiotics in wastewater.The removal mechanism of antibiotics from wastewater by modified biochar was also ana-lyzed,including electrostatic interaction,H bond,π-π interaction,and surface complexation.Some short-comings of modified biochar were summarized and the corresponding prospects for future work were put forward,so that modified biochar could be better used in the treatment of antibiotics in wastewater and play a greater role in environmental remediation.
