It is important to develop new materials for analytical sample preparation for the separation, detection and preconcentration of toxic metals from food, and environmental materials. Metal organic frameworks are a class of crystalline materials used in the analysis of toxic metals in recent years, with their porosity, enormous internal surface areas, adsorption capacities, functionalization properties, and stability. MOFs are promising adsorbents for the fast and efficient extraction of heavy metal ions from complex samples in food safety and environmental pollution management. This review describes recent developments in the use of MOFs in the analysis of toxic metals in food and environmental samples. Thus, it will lead to the planning of new studies for the use of MOFs in different matrices.

开发用于从食品和环境材料中分离、检测和预浓缩有毒金属的分析样品制备的新材料非常重要。金属有机骨架是近年来用于分析有毒金属的一类结晶材料，具有多孔性、巨大的内表面积、吸附能力、功能化特性和稳定性。MOF 是一种很有前途的吸附剂，可用于从食品安全和环境污染管理中的复杂样品中快速有效地提取重金属离子。本综述描述了使用 MOF 分析食品和环境样品中有毒金属的最新进展。因此，这将导致规划在不同基质中使用 MOF 的新研究。
