改性生物炭对水环境中抗生素类药物的吸附研究进展

由抗生素滥用引起的药物污染对人类健康和生态系统构成潜在威胁。吸附法是去除水环境中有机污染物的最有效方法之一。生物炭作为一种廉价高效的吸附材料,改性可使其吸附性能显著提升,改性生物炭对抗生素的吸附特性及机理被广泛研究和应用。在对生物炭制备及其改性方法进行回顾的基础上,系统论述了改性生物炭对典型抗生素药物的吸附性能及机制等方面的研究进展,并对生物炭的再生及其经济性进行分析,以期为新型高效生物炭的吸附机制和材料研发提供借鉴。

ADSORPTION OF ANTIBIOTIC DRUGS IN WATER ENVIRONMENT BY MODIFIED BIOCHAR:A REVIEW

Drug contamination caused by the overuse of antibiotics poses a potential threat to human health and ecosystems. Adsorption is one of the most effective methods to remove organic pollutants from the water environment, as a cheap and efficient adsorption material, adsorption properties of the biochar has been significantly improved after modification. The adsorption characteristics and mechanism of the modified biochar to antibiotics have been widely studied and applied. On the basis of a review on the preparation and modification technologies of biochars, this paper systematically discussed the progress and deficiency of the adsorption properties and mechanism of the modified biochar to typical antibiotic drugs, and analyzed the recycling and economic benefits of biochar, in order to provide guidance and reference for the research and development of new high-efficiency biochar adsorption mechanism and materials.
