中文摘要:

      有机锡化合物作为金属有机化合物的一种, 其使用范围广、形态差异大, 且由其引起的潜在危害不可估量。现代农业用有机锡化学品与食品的质量安全密切相关, 由于不合理、不规范使用农药而导致的残留超标问题一直为大众所关注。用于农业生产的有机锡农药虽然只是有机锡有机化合物的一小部分, 但是有机锡农药不合理的使用, 依然会对人体及环境造成巨大的危害。因此, 选择合理的样品前处理技术、仪器检测技术对准确识别并科学分析食品中有机锡农药分布特征, 对监管样品中有机锡农药质量安全具有重要意义。本文从萃取、衍生、净化、检测4个方面总结概括了有机锡农药分析方法研究进展, 旨在为有机锡农药污染的监测和监管提供技术参考。

英文摘要:

      Organotin compounds, as a kind of organometallic compounds, are widely used and have great morphological differences, and the potential harm caused by them is immeasurable. Organotin chemicals for modern agriculture are closely related to the quality and safety of food. The problem of excessive residue caused by unreasonable and nonstandard use of pesticides has always been concerned by the public. Although organotin pesticides used in agricultural production are only a small part of organotin organic compounds, the unreasonable use of organotin pesticides will still cause great harm to human body and environment. Therefore, the selection of reasonable sample pretreatment technology and instrument detection technology is of great significance to accurately identify and scientifically analyze the distribution characteristics of organotin pesticides in food and supervise the quality and safety of organotin pesticides in samples. This paper summarized the research progress of organotin pesticide analysis methods from 4 aspects: Extraction, derivation, purification and detection, in order to provide technical references for the monitoring and supervision of organotin pesticide pollution.
