水环境中抗生素的分析检测技术研究进展

Research Progress on Analytical Detection Techniques of Antibiotics in Water

抗生素作为环境介质中的一种典型的新污染物,已成为国内外学者研究的热点。抗生素种类繁多,在水环境中浓度较低,且存在基质干扰,对分离、富集与净化技术和分析仪器提出更高的要求。文章综述了水环境中抗生素的前处理方法和仪器分析检测方法,结合各类抗生素的化学性质对前处理技术和液相色谱检测技术的优缺点进行了重点阐述,并对方法中可能影响萃取效率和分析检测的各种因素进行了分析总结,最后对各种环境介质中抗生素及其代谢物监测和治理技术的研究以及标准体系的建立进行了展望。

Due to the broad-spectrum activity of antibiotics,antibiotics are widely used to treatment diseases or promote animal growth worldwide in both human and veterinary medicine.The massive and widespread usage of antibiotics have resulted in continuous access and accumulation in the environment,such as water,soil and sediment.Based on the above situation antibiotics have seriously threatened the ecological environment and human health.Antibiotics have become the research focus of domestic and foreign scholars in recent years as a typical emerging pollutant in environmental media.Because of the diverse range of antibiotics with various characteristics,as well as their presence at low concentrations in the environment and matrix interference,higher requirements are put forward for separation and enrichment and purification technology of antibiotics and analytical instruments.The various pretreatment methods and instrumental analysis of antibiotics in water environment samples are summarized,with key elaborate on the advantages and disadvantages of pretreatment methods and liquid chromatography techniques in combination with the properties of various antibiotics.Additionally,the potential factors influencing the extraction performance and analysis of antibiotics are analyzed.Finally,the research for monitoring and management of antibiotics and their metabolites in different environmental media and the establishment of standard methods are prospected.
