Abstract

Sorptive pre-concentration of pesticide residues in food and environmental samples is increasingly gaining momentum. This can be attributed to fact that most sorptive extraction techniques are solvent-free as well as the availability of emerging sorbents with relatively high adsorption capacities. Metal organic frameworks (MOFs) are among the emerging sorbents that have captured the interests of many researchers during pesticide analysis. There are many types of MOFs that have been used by researchers to pre-concentrate pesticides in food and environmental samples. Some researchers have successfully used MIL-based MOFs during sorptive extraction of pesticides in complex matrices. This review gives a detailed discussion of their application during pesticide pre-concentration. Other researchers have used the ZIF series of MOFs for the sorptive pre-concentration of pesticides in food and environmental samples. The utilisation of the ZIF series of MOFs during pesticide pre-concentration is well-articulated in this review. The review also devoted to the application of UiO and HKUST series of MOFs during the pre-concentration of pesticides in food and environmental samples. In addition, the challenges associated with the use of MOFs during sorptive pre-concentration of pesticides are also discussed in this review.

用金属有机骨架吸附剂从食品和环境样品中吸附提取农药

食品和环境样品中农药残留的吸附预浓缩越来越受到重视。这可以归因于大多数吸附萃取技术是无溶剂的，以及具有相对高吸附能力的新兴吸附剂的可用性。金属有机框架(mof)是一种新兴的吸附剂，在农药分析中引起了许多研究人员的兴趣。有许多类型的MOFs已被研究人员用于预先浓缩食品和环境样品中的农药。一些研究人员已经成功地将mof用于复杂基质中农药的吸附提取。本文对其在农药预浓缩中的应用进行了详细的讨论。其他研究人员已将ZIF系列mof用于食品和环境样品中农药的吸附预浓缩。本文综述了ZIF系列mof在农药预浓缩中的应用。本报告亦介绍了UiO及科大系列MOFs在食物及环境样本中预浓缩除害剂的应用。此外，本文还讨论了在农药吸附预浓缩过程中使用MOFs所面临的挑战。
